How to normalize fancy Unicode text back to regular text?

@Dean-Corso Understood but at least for the two examples you provided the search/replace is:
** Search: (?-i)(?:(𝘈|𝘼)|(𝘉|𝘽)|(𝘊|𝘾)|(𝘋|𝘿)|(𝘌|𝙀)|(𝘍|𝙁)|(𝘎|𝙂)|(𝘏|𝙃)|(𝘐|𝙄)|(𝘑|𝙅)|(𝘒|𝙆)|(𝘓|𝙇)|(𝘔|𝙈)|(𝘕|𝙉)|(𝘖|𝙊)|(𝘗|𝙋)|(𝘘|𝙌)|(𝘙|𝙍)|(𝘚|𝙎)|(𝘛|𝙏)|(𝘜|𝙐)|(𝘝|𝙑)|(𝘞|𝙒)|(𝘟|𝙓)|(𝘠|𝙔)|(𝘡|𝙕)|(𝘢|𝙖)|(𝘣|𝙗)|(𝘤|𝙘)|(𝘥|𝙙)|(𝘦|𝙚)|(𝘧|𝙛)|(𝘨|𝙜)|(𝘩|𝙝)|(𝘪|𝙞)|(𝘫|𝙟)|(𝘬|𝙠)|(𝘭|𝙡)|(𝘮|𝙢)|(𝘯|𝙣)|(𝘰|𝙤)|(𝘱|𝙥)|(𝘲|𝙦)|(𝘳|𝙧)|(𝘴|𝙨)|(𝘵|𝙩)|(𝘶|𝙪)|(𝘷|𝙫)|(𝘸|𝙬)|(𝘹|𝙭)|(𝘺|𝙮)|(𝘻|𝙯))

It looks messy because
𝘏𝘦𝘭𝘭𝘰 𝘕𝘰𝘵𝘦𝘱𝘢𝘥 𝘱𝘭𝘶𝘴 𝘱𝘭𝘶𝘴 𝘤𝘰𝘮𝘮𝘶𝘯𝘪𝘵𝘺 and 𝙃𝙚𝙡𝙡𝙤 𝙉𝙤𝙩𝙚𝙥𝙖𝙙 𝙥𝙡𝙪𝙨 𝙥𝙡𝙪𝙨 𝙘𝙤𝙢𝙢𝙪𝙣𝙞𝙩𝙮 are using characters from the Unicode Mathematical Alphanumeric Symbols block which ranges from U+1D400 to U+1D7FF. As they are using Unicode characters higher than U+FFFF the Notepad++ editor has glitches. The search/replace I provided works around those glitches by creating 52 separate buckets, 26 for upper case A-to-Z, and 26 more for lower case a-to-z. Each of the 52 buckets has a list of “fancy” Unicode characters that can get matched and filed into that bucket and in the replacement part each of the 52 buckets replaces the bucket contents with a plain ASCII A-to-Z or a-to-z.

I’m not sure if Python can deal with characters above U+FFFF. If it can, then that is likely easier to work with and to maintain as most of that block looks like A-to-Z ranges that could each get translated to A-to-Z ASCII.

Ideally, Notepad++'s convert to ANSI code gets updated to be aware of those character ranges.

What is described in this topic is not, at all, what Convert to ANSI does.

For example, at Normalize Unicode Text, if you paste this in the left side:

ßášï©

you will see:

BasiC

on the right side.

If your default code page is CP1252 (common for Western Europe and the US) and you open a new tab in Notepad++, set it to UTF-8, paste in ßášï© and then convert to ANSI… nothing will change.

(However, something odd does happen on my system if I save it ANSI — when I open it again, Notepad++ detects it as Greek/ISO-8859-7; I have to select Western European / Windows-1252 to see it properly. I don’t know why Notepad++ thought it was more likely to be Greek than my default code page; all those symbols are in Windows-1252.)

Nothing will seem to change for ßášï© because all six characters in your example are available in ANSI.

ß is ANSI DF and Unicode U+00DF
á is ANSI E1 and Unicode U+00E1
š is ANSI 9A and Unicode U+0161. Unicode U+009A is used for SINGLE CHARACTER INTRODUCER.
ï is ANSI EF and Unicode U+00EF
© is ANSI A9 and Unicode U+00A9

When I put UTF-8 encoded ßášï© into a file, convert to ANSI, and save it, then I see that the file contains \xDF \xE1 \x9A \xEF \xA9 which is what I expect.

You are correct in that when I load it into Notepad++ then it’s identified as ISO-8859-7. I don’t think the misidentification is a concern as the file is very small. The code only has six bytes to work with and all six are unusual for ANSI text.

On that website I can see it’s running a JavaScript with all functions to do that operation what also includes all of these Unicode letters in a array variable called “var unicodeLetters”. Maybe it’s possible to adapt this code to make a python script etc. In the script is also a link to a UTF-8 encoder/decoder you can enter text to get encoded hex bytes out. In case of entering “𝗗” I get 4 hex bytes “\xF0\x9D\x97\x97” and in case of “ßášï©” I get “\xC3\x9F\xC3\xA1\xC5\xA1\xC3\xAF\xC2\xA9” out.

Here the script the website is using.

Maybe it could help to adapt it and create something for npp.

PS: Thank you for that one reputation point @mkupper. Now I could also post links.

I tried already to enter specific python command combo in python console but the results I got out was just question marks using the “NFKD”.

If you used the default PythonScript 2.0.0.0 from the Plugins Admin, then your unicode strings in your test would need to be marked as u'𝘏𝘦𝘭𝘭𝘰 𝘕𝘰𝘵𝘦𝘱𝘢𝘥 𝘱𝘭𝘶𝘴 𝘱𝘭𝘶𝘴 𝘤𝘰𝘮𝘮𝘶𝘯𝘪𝘵𝘺' in order for Python 2.7 to know it was unicode.

But when i tried even with that in the default PythonScript plugin, it wouldn’t normalize that string (though it could normalize some others).

When i switch to a copy of Notepad++ with PythonScript 3.0.17 (using Python 3.12, which doesn’t need fancy string syntax for unicode strings), and ran an example script from here, I got the expected output:

Python 3.12.1 (tags/v3.12.1:2305ca5, Dec  7 2023, 22:03:25) [MSC v.1937 64 bit (AMD64)]

So to be able to normalize your particular characters, you must use PythonScript 3.x, which you can download from here.

You’re correct, of course. I should have worded that more carefully. My point was that the characters themselves don’t change when you convert from Unicode to ANSI, only the internal representations; my example didn’t include characters not in the local code page, which just change to question marks.

The original poster desires to change the characters themselves, not just their internal representations; that is not the purpose of Convert to ANSI.

There is a jN (JavaScript for Notepad++) plugin available through Plugins Admin. I was never quite able to grasp, from the documentation, how to use it, but it appears very powerful. If you know Javascript and have found the relevant scripts in the web page, you might be able to use it to do what you need.

Some characters do change. Copy/paste the following into a UTF-8 encoded tab or file. It should be the same as when you see here on the forums.

Copy/paste it into an ANSI encoded tab or file. You should see plain ASCII.

On the UTF-8 encoded tab do an Encoding / Convert to ANSI. The first two lines are plain ASCII but the rest are not ASCII and are characters that do not have a direct mapping into the same character/glyph in ANSI.

Nothing visually will change, but the underlying bytes of the file will all change.
EDIT: Oops, this has already been said. :-)

if I save it ANSI — when I open it again, Notepad++ detects it as Greek/ISO-8859-7

Yes, the encoding autodetection of Notepad++ has long been a target of scorn because it can fail in such ways, but apparently autodetection is not always possible, or at least can be extremely difficult…

Hello, @dean-corso, @peterjones, @mkupper, @alan-kilborn, @coises and All,

In Unicode v15.1, the Mathematical Alphanumeric Symbols bliock contains 1024 characters, between U+1D400 and U+1D7FF, whose 28 are unassigned. Refer to :

https://www.unicode.org/charts/PDF/U1D400.pdf

Of course, we could generate from within N++, some regexes in order to transform these characters into standard ASCII characters !

If we restrict our goal to latin letters and digits of this block, we would use the ranges 1D400 - 1D6A3 and 1D7CE - 1D7FF

However, the N++ regex engine cannot directly handle characters over the BMP ( so chars with code over \x{FFFF} )

You need to use its surrogate pair characters to match a specific character

For example, the char :

𝑻

Cannot be found with the regex \x{1D47B}. Luckily, you can match it with the regex \x{D835}\x{DC7B}, using the Unicode Surrogate Area

So, we could build these 3 giant regex S/R, below, which, in theory, could replace any fancy character of this Unicode block by standard letters and digits

However, regarding the regexes which concern the letters, this would NOT be possible because the search exceeds the N++ limit of 2,046 chars !

We could, also, divide this work in several macros, which would consecutively change all these chars but it would be a tedious work, anyway !

So personally, I advice you to simply use this on-line tool :

https://onlinetools.com/unicode/normalize-unicode-text

To get normal text and this other one :

https://onlinetools.com/unicode/generate-unicode-text

To do the reverse operation, if necessary

Have also a look to an old post of mine :

OP has already said that such usage is undesirable; well, I think that is what he is saying with:

Otherwise we are depending on other sources like those websites who support that function and that a disadvantage for npp and npp users

Isn’t the true answer what @PeterJones has shown is possible, with a script?
Such a script could act on selected text when the script is run, and replace that text with the normalized text…pretty simple concept.

@mkupper said in How to normalize fancy Unicode text back to regular text?:

Some characters do change. Copy/paste the following into a UTF-8 encoded tab or file. It should be the same as when you see here on the forums.

I stand corrected. I did not at all expect that to happen. It’s my understanding of “convert to ANSI” that is confused. I apologize.

Very strange:

Open Notepad++, convert empty tab to UTF-8, copy your text, paste into tab, I see all the characters.

Copy your text, open Notepad++, convert empty tab to UTF-8, paste into tab, I see only ASCII characters.

I have no idea what is going on here.

Might as well just make the script now, save others time.

As noted in the docstring of the code, the most obvious difference between NFKD and NFKC seems to be treatment of characters with combining diacritics or umlauts or what have you. Which form is better seems really context-dependent to me; if you’re sorting text, you probably want ö to be an o and then an umlaut (so that ö sorts after o and before p as expected), but if you’re doing regular expression search, you might prefer it to be a single character.

Hi, @alan-kilborn,

I completely agree with your last assumption and that why I had already upvoted @peterjones’s post and I now upvote to @mark-olson’s solution too !

Hi guys,

thanks again for your help. Really nice from you all.

@PeterJones

Thanks for hint about the python script versions. I did download the latest pre version as you but could not make the same steps like you did to enter your example lines. Got some errors trying to exec the print command (getting expand error on for statement etc). Just did enter same as you. Maybe some space issue or something not sure. But good to know that I needed to use a higher python 3x version so I was still using the older 2x version.

@Mark-Olson

Thank you for that example script. I tried that one and it seems to work. Great! The results are very good for me and its working for some of those different symbol styles (not all) to get a rid of those symbol text at all or some mixed plain text with symbol text etc. I mean the script works same like those few websites I found to normalize the symbol text to plain text. That’s very good and I don’t need to use those websites anymore and that was one of my goals. Would be good when npp could make a build in function for that in any future releases if possible.

If you copy/pasted the PythonScript console results (including the version information) like I did above, I bet someone could tell you what happened

Ok I tried again and now I get this out…

…but don’t see the printed output like you have. Did I miss anything to enter in this case?

PS: About that error before, I see I forgot to enter another white space before last print command.

PeterJones

@Dean-Corso ,

If your PythonScript console prompt is still ... instead of >>>, you will need to enter a blank line (no whitespace) to tell the console to end the loop. It won’t run the loop until you do.
