Invisible characters unwanted
-
I think what you’re missing is that your font doesn’t have a glyph for the character, so shows the
?in a box.My font, DejaVu Sans Mono, has a glyph for that character, which is a zero-width glyph, so you cannot see it (because it’s there, but zero-width). But I can highlight it (see the little green highlight on the first line, and the “Sel: 1|1” on the status bar.
@Nathan-Harvey , I think Notepad++ and my font are doing the right thing: there is a character (Zero-Width Space), and it is being shown, as zero-width. It’s not a control-character, so it doesn’t have a default
CRLF-style box-glyph from show-all-characters.However, using the PythonScript plugin (that Claudia’s screenshot implied), you can run
editor.setRepresentation(u'\u200B', "ZWS")to get it to replace the normal zero-width space withZWSin a black box (similar to theCRandLFboxes). To clear that alternate representation,editor.clearRepresentation(u'\u200B'). (There is similar notation for the NppExec plugin as well, but I do not know how to represent a unicode string in its syntax.)By saving that to a script, and using the PythonScript Configuration menu to add that script to the
Plugins > PythonScriptmenu, you can actually then assign a keyboard shortcut usingSettings > Shortcut Mapper > Plugin Commands. If you make two scripts# script = Show ZeroWidth Characters (give them a non-zero-width representation) editor.setRepresentation(u'\u200B', "ZWS") editor.setRepresentation(u'\u200C', "ZWNJ") editor.setRepresentation(u'\u200D', "ZWJ") editor.setRepresentation(u'\uFEFF', "ZWNBSP") # script = Default ZeroWidth Characters (return them to their zero-width glyph from the selected font) editor.clearRepresentation(u'\u200B') editor.clearRepresentation(u'\u200C') editor.clearRepresentation(u'\u200D') editor.clearRepresentation(u'\uFEFF')you can get all the “zero width” unicode characters that I can find to toggle visibility

Peter, thank you very much for your insight.
You could be and I already start thinking you are right about the glyph and my used font.
I still feel it should be the other way around as I don’t like to have an invisible char in my code
and wondering why it doesn’t do what it is supposed to do but than, on the other side, it doesn’t make sense to have a zero-width char. Hmmm.
I guess I’m good as I can use my font or using setRepresentation function to see any “invisible” chars :-)
Your explanation makes sense - absolutely.Thank you very much.

Also, if you want one command to do the normal
Show All Charactersplus showing these four Zero Width characters,# script = Show All Characters (including ZeroWidth) editor.setRepresentation(u'\u200B', "ZWS") editor.setRepresentation(u'\u200C', "ZWNJ") editor.setRepresentation(u'\u200D', "ZWJ") editor.setRepresentation(u'\uFEFF', "ZWNBSP") # if you want to _also_ show all characters with this script, # first pick a different View > Show Symbols option, # then pick this one (each is a toggle, so don't want to accidentally hide all characters if show-all was already selected) notepad.menuCommand(MENUCOMMAND.VIEW_EOL) notepad.menuCommand(MENUCOMMAND.VIEW_ALL_CHARACTERS)And similarly to un-set
Show All Charactersas well as clearing the four Zero Width representations:# script = Don'tShow All Characters (including ZeroWidth) editor.clearRepresentation(u'\u200B') editor.clearRepresentation(u'\u200C') editor.clearRepresentation(u'\u200D') editor.clearRepresentation(u'\uFEFF') # if you want to _also_ hide all characters with this script, # first pick a different View > Show Symbols option, # then pick this one twice (each is a toggle, so don't want to accidentally show all characters if show-all was already cleared) notepad.menuCommand(MENUCOMMAND.VIEW_EOL) notepad.menuCommand(MENUCOMMAND.VIEW_ALL_CHARACTERS) notepad.menuCommand(MENUCOMMAND.VIEW_ALL_CHARACTERS)As explained in my comments, I use the VIEW_EOL to change out of VIEW_ALL_CHARACTERS, no matter what the state of the VIEW_ALL_CHARACTERS toggle is; then I use VIEW_ALL_CHARACTERS once to set it or twice to clear it. If, instead, you’d like your DontShowAllCharacters to revert to “Show EOL” or “Show Whitespace and Tab”, then instead of VIEW_EOL/VIEW_ALL_CHARACTERS/VIEW_ALL_CHARACTERS sequence of three, you could just use VIEW_EOL (a sequence of one to show EOL) or VIEW_TAB_SPACE. (Though, to be safe, you might want a two-sequence of VIEW_ALL_CHARACTERS/VIEW_EOL or VIEW_ALL_CHARACTERS/VIEW_TAB_SPACE. It would be easier if there were a notepad.getMenuCommandState() or similar command that reads back the current state of a toggled menu command.)
-
thx,
there are editor.getViewEOL() and editor.getViewWS() functions available
to retrieve current state. But instead of using setView… I would recommend using
notepad.menuCommand(MENUCOMMAND…) to be in sync with notepad++ itself.Cheers

I’ve noticed that after doing an
editor.setRepresentation()it shows the new character representation in the currently active tab, but if I switch tabs to one which also has characters that should be shown by this, they aren’t shown. Switching back to the tab I started in, the representation I set has also disappeared.I think I know why this is (well, kinda, :-) ), but I’m surprised it wasn’t mentioned before in this thread.

Here’s a little script to avoid that problem, I call it
SetRepresentationForSpecialCharacters.py:# -*- coding: utf-8 -*- from Npp import editor, notepad, NOTIFICATION class SRFSC(object): def __init__(self): notepad.callback(self.callback_npp_BUFFERACTIVATED, [NOTIFICATION.BUFFERACTIVATED]) self.callback_npp_BUFFERACTIVATED(None) def callback_npp_BUFFERACTIVATED(self, args): editor.setRepresentation(u'\u200B', "ZWS") editor.setRepresentation(u'\u200C', "ZWNJ") editor.setRepresentation(u'\u200D', "ZWJ") editor.setRepresentation(u'\u200E', "LTR") # left-to-right mark editor.setRepresentation(u'\uFEFF', "ZWNBSP")I run it from my
startup.pywith this segment of code:import SetRepresentationForSpecialCharacters SetRepresentationForSpecialCharacters.SRFSC() -
@Alan-Kilborn said in Invisible characters unwanted:
editor.setRepresentation(u'\u200E', "LTR") # left-to-right mark`Apparently this LTR issue is really annoying to you. :-)
Looking at http://www.fileformat.info/info/unicode/block/general_punctuation/images.htm, there are other control characters in that block, so if your data is more varied, I might expand that to:
# zero width in name editor.setRepresentation(u'\u200B', "ZWS") editor.setRepresentation(u'\u200C', "ZWNJ") editor.setRepresentation(u'\u200D', "ZWJ") editor.setRepresentation(u'\uFEFF', "ZWNBSP") # also zero width editor.setRepresentation(u'\u2060', "WJ") # word joiner (separate from ZWJ, but still claims zero width) # directional controls and other toggles editor.setRepresentation(u'\u200E', "LTR") # left-to-right mark editor.setRepresentation(u'\u200F', "RTL") # right-to-left mark editor.setRepresentation(u'\u202A', "EMBL") # left-to-right embedding editor.setRepresentation(u'\u202B', "EMBR") # right-to-left embedding editor.setRepresentation(u'\u202C', "EMBP") # pop directional formatting editor.setRepresentation(u'\u202A', "OVRL") # left-to-right override editor.setRepresentation(u'\u202B', "OVRR") # right-to-left override editor.setRepresentation(u'\u2066', "ISOL") # left-to-right isolate editor.setRepresentation(u'\u2067', "ISOR") # right-to-left isolate editor.setRepresentation(u'\u2068', "ISO1") # first strong isolate editor.setRepresentation(u'\u2069', "ISOP") # pop directional isolate editor.setRepresentation(u'\u206A', "SYMI") # inhibit symmetric swapping editor.setRepresentation(u'\u206B', "SYMA") # activate symmetric swapping editor.setRepresentation(u'\u206C', "ARAI") # inhibit arabic form shaping editor.setRepresentation(u'\u206D', "ARAA") # activate arabic form shaping editor.setRepresentation(u'\u206E', "SHNA") # national digit shapes editor.setRepresentation(u'\u206E', "SHNO") # nominal digit shapesBut, most important is to include the characters that you, as the user of the script, might run across.

Hello, @peterjones, @alan-kilborn and All,
From these two links :
https://www.unicode.org/charts/PDF/U2000.pdf
https://www.unicode.org/charts/PDF/UFE70.pdf
I just rewrote these
26special characters :-
By increasing Unicode code-point order
-
With their exact code-points ( some typos corrected )
-
With their normalized Unicode character representation
So, here is a new version of the @alan-kilborn’s
SetRepresentationForSpecialCharacters.pyfile, with the merged lines from the @peterjones’s script, without using thestartup.pyfile :# -*- coding: utf-8 -*- from Npp import editor, notepad, NOTIFICATION class SRFSC(object): def __init__(self): notepad.callback(self.callback_npp_BUFFERACTIVATED, [NOTIFICATION.BUFFERACTIVATED]) self.callback_npp_BUFFERACTIVATED(None) def callback_npp_BUFFERACTIVATED(self, args): # FORMAT chars editor.setRepresentation(u'\u200B', "ZWSP") # zero width space editor.setRepresentation(u'\u200C', "ZWNJ") # zero width non-joiner editor.setRepresentation(u'\u200D', "ZWJ") # zero width joiner editor.setRepresentation(u'\u200E', "LRM") # left-to-right mark editor.setRepresentation(u'\u200F', "RLM") # right-to-left mark editor.setRepresentation(u'\u202A', "LRE") # left-to-right embedding editor.setRepresentation(u'\u202B', "RLE") # right-to-left embedding editor.setRepresentation(u'\u202C', "PDF") # pop directional formatting editor.setRepresentation(u'\u202D', "LRO") # left-to-right override editor.setRepresentation(u'\u202E', "RLO") # right-to-left override editor.setRepresentation(u'\u2060', "WJ") # word joiner ( zero width no-break space ) # INVISIBLE chars editor.setRepresentation(u'\u2061', "FA") # function application editor.setRepresentation(u'\u2062', "IT") # invisible times editor.setRepresentation(u'\u2063', "IS") # invisible separator editor.setRepresentation(u'\u2064', "IP") # invisible plus # FORMAT chars editor.setRepresentation(u'\u2066', "LRI") # left-to-right isolate editor.setRepresentation(u'\u2067', "RLI") # right-to-left isolate editor.setRepresentation(u'\u2068', "FSI") # first strong isolate editor.setRepresentation(u'\u2069', "PDI") # pop directional isolate # DEPRECATED chars editor.setRepresentation(u'\u206A', "ISS") # inhibit symmetric swapping editor.setRepresentation(u'\u206B', "ASS") # activate symmetric swapping editor.setRepresentation(u'\u206C', "IAFS") # inhibit arabic form shaping editor.setRepresentation(u'\u206D', "AAFS") # activate arabic form shaping editor.setRepresentation(u'\u206E', "NADS") # national digit shapes editor.setRepresentation(u'\u206F', "NODS") # nominal digit shapes # SPECIAL char editor.setRepresentation(u'\uFEFF', "BOM") # byte order mark ( zero width no-break space : deprecated, see U+2060 ) notepad.menuCommand(MENUCOMMAND.VIEW_ALL_CHARACTERS) notepad.menuCommand(MENUCOMMAND.VIEW_ALL_CHARACTERS) SRFSC()

On the other hand, you may quickly verify if some special characters exist in current file, using the
Markdialog :- MARK
[\x{200B}-\x{200F}\x{202A}-\x{202E}\x{2060}-\x{2064}\x{2066}-\x{206F}\x{FEFF}]
- MARK
=> You should see some thin
redmarks and , since thev7.9.2N++ version, you can copy all these chars in a new tab, for further examination, with theCopy Marked Textbutton !-
A third solution could be to perform a regex S/R ( which can be recorded as a macro) to replace any of these special characters with their Unicode representation :
-
SEARCH
(\x{200B})|(\x{200C})|(\x{200D})|(\x{200E})|(\x{200F})|(\x{202A})|(\x{202B})|(\x{202C})|(\x{202D})|(\x{202E})|(\x{2060})|(\x{2061})|(\x{2062})|(\x{2063})|(\x{2064})|(\x{2066})|(\x{2067})|(\x{2068})|(\x{2069})|(\x{206A})|(\x{206B})|(\x{206C})|(\x{206D})|(\x{206E})|(\x{206F})|(\x{FEFF}) -
REPLACE
(?1[ZWSP])(?2[ZWNJ])(?3[ZWJ])(?4[LRM])(?5[RLM])(?6[LRE])(?7[RLE])(?8[PDF])(?9[LRO])(?10[RLO])(?11[WJ])(?12[FA])(?13[IT])(?14[IS])(?15[IP])(?16[LRI])(?17[RLI])(?18[FSI])(?19[PDI])(?20[ISS])(?21[ASS])(?22[IAFS])(?23[AAFS])(?24[NADS])(?25[NODS])(?26[BOM]) -
Once the characters have been noted and/or the lines bookmarked, for further analyze, then just undo the replacements with
Ctrl + Z

Is it your intent with your last posting to say that, with the PDFs from unicode.org, we now have a “complete” list of invisible characters, and a script can be made that covers them all, using correct abbreviations in their N++ representations?
At first look, it seems that anything in those docs that is shown inside a “dashed box”, e.g.:
is a good candidate for a new representation being assigned in a N++ script like the ones above?
If this is the case, I’m surprised that in the script you presented, not all of the seemingly invisible characters from the documents are in the script.
EDIT: Hmm, not sure now about the “dashed box” as I just noticed some dashed boxes in the doc containing things like
,and+, so probably the dashed box does not truly identify something as an “invisible character”. -
Hi, @alan-kilborn, @peterjones and All,
From the
UnicodeData.txtfile https://www.unicode.org/Public/UCD/latest/ucd/UnicodeData.txtI just extract the lines relative to any character which has a General Category property
CforZs(3rdfield of the list ), i.e. theFormat_ControlandSpace_Separatorcharacters. Indeed, depending of the current font used, these characters may be :-
Not displayed at all ( Invisible )
-
Displayed as a question mark, inside a square or lozenge
-
Displayed as a white square box
-
Displayed with a wrong width ( case of a space char )
As a remainder, below, here is a table, giving all values of the Unicode

Hi All,
Continuation …
From this last table, we can reasonably ignore :
-
The space and soft hyphen characters
-
Some musical characters
-
All the characters, specific to a language, modern or archaic
-
The tag characters, whose usage is strongly discouraged by the
Unicode consortium.

I did not investigate in the S/R, because of the number of chars to handle (
50) and because I’m just feeling… lazy for such a task !However with the
Markoperation, which helps you to locate exactly where are these special characters and thePythonscript which clearly identify them, you should be safe with your file’s contents ;-))

This thread largely talks about making “invisible” characters visible.
Recently I had a need/desire to make characters with a visible component invisible, i.e. “go the other way”.
Example:
So for the above, I’d like to “turn off” the control characters and focus only on the “meat” of the data:
This is only for visualization purposes; I’m not editing this data.
Long story short is I ran into trouble doing this. I found I can change the representation of the characters, using PythonScript, e.g., executing
editor.setRepresentation(u'\u0002', 'startxmit')will then show:
But my guess at what was needed to hide the U+0002 character entirely didn’t work:
editor.setRepresentation(u'\u0002', '')produces:
which is “better” but still has a visual component.
editor.clearRepresentation(u'\u0002')only brings back the default visualizaton ofSTX.Any ideas on how to solve this, i.e., eliminate the visual component of a control character?
-
Adhoc, the only thing I can think of is to give the control chars a style and set the visible property to false.
Practically like the error list lexer does with the ANSI sequences. -
@Ekopalypse said in Invisible characters unwanted:
Adhoc, the only thing I can think of is to give the control chars a style and set the visible property to false.
Practically like the error list lexer does with the ANSI sequences.That sounds like a lot of work, both coding wise and runtime wise. I was hoping that I was misunderstanding some simple thing about how Scintilla does “representation”, but from lack of replies, and direction of the one reply, it appears I am not missing that “simple thing”.
I think it is odd that Scintilla basically forces me to see always see “control characters”, but never shows me certain UTF-8 characters.
-
Someone else found the solution for me:
- set the control character’s representation to the “zero-width space” character (so it has no visual component – but it will have a small “inverse video” artifact on-screen)
- set the representation appearance to plain text (to avoid the inverse video)
Although, to script this (as I tend to do) is difficult as the set-representation-appearance Scintilla command is not yet available as an
editorcommand in the PythonScript versions that are current as of this writing.
