Now, let’s suppose that, from the list, below, you would like to replace these 14 Unicode characters, on the left, with their similar standard character, on the right :
| 00A6 | ¦ | BROKEN BAR | 007C | | | VERTICAL LINE |
| 00BD | ½ | VULGAR FRACTION ONE HALF | | 1/2 | |
| 2000 | | EN QUAD | | \x20{2} | |
| 2001 | | EM QUAD | | \x20{4} | |
| 2018 | ‘ | LEFT SINGLE QUOTATION MARK | 0027 | ' | APOSTROPHE |
| 2019 | ’ | RIGHT SINGLE QUOTATION MARK | 0027 | ' | APOSTROPHE |
| 201C | “ | LEFT DOUBLE QUOTATION MARK | 0022 | " | QUOTATION MARK |
| 201D | ” | RIGHT DOUBLE QUOTATION MARK | 0022 | " | QUOTATION MARK |
| 203D | ‽ | INTERROBANG | | !? | |
| 2264 | ≤ | LESS-THAN OR EQUAL TO | | <= | |
| 2265 | ≥ | GREATER-THAN OR EQUAL TO | | >= | |
| 2639 | ☹ | WHITE FROWNING FACE | | :-( | |
| 263A | ☺ | WHITE SMILING FACE | | :-) | |
| FFFD | � | REPLACEMENT CHARACTER | 003F | ? | QUESTION MARK |
Then :
Open the Replace dialog, in N++ ( Ctrl + H )
Type in the regex (¦)|(½)|( )|( )|(‘)|(’)|(“)|(”)|(‽)|(≤)|(≥)|(☹)|(☺)|(�), in the Find what: zone
Type in the regex (?1|)(?{2}1/2)(?3\x20\x20)(?4\x20\x20\x20\x20)(?5')(?6')(?7")(?8")(?9!?)(?{10}<=)(?{11}>=)(?{12}\:-\()(?{13}\:-\))(?{14}?), in the Replace with: zone
Tick the Wrap around option
Select the Regular expression search mode
Click, once , on the Replace All button, or several times on the Replace button
Et voilà !
Notes :
In search, we, simply, put each character, to be replaced, between round parentheses, in order to be stored as group 1, 2 and so on…
In replacement, we use a special conditional syntax (?#xxxx:yyyy) or (?{#..#}xxxx:yyyy), where :
# or #...# represents a group number
The part xxxx is rewritten, if group # or #...# exists
The part yyyy is rewritten, if group # or #...# does not exist
In our case, the ELSE part, in each conditional replacement, is not present
If a part xxxx or yyyy contains the character :, ( or ), it must be escaped ( preceded ) with a \ symbol
For the second conditional replacement, I used the syntax (?{2}1/2), on purpose ! Indeed, if I would have used the (?21/2) syntax, the regex engine would have, wrongly, tried to replace any searched group 21 with the /2 string !!
To end with, note that quantifiers, as {#}, do not work, in replacement. So we need to change, for instance, the \x20{2} syntax ( 2 space characters) by the simple \x20\x20 one !
