Every now and then I try to remove a space or non-breaking space via a regex. Unfortunately it does not work in Studio. Why? It works in .Net. Can this be repaired?
Here is an example: I try to remove the space between +/- and a number (eg. + 23 % should be +23 %)
Regex: (?<!\d\s?)([\+-])\s(\d)
Replace with: $1$2
Your best bet is to use the SDLXLFF Toolkit from the appstore. The use of backreferences in Studio search & replace has a bug and won't work. I know it's been worked on so should be fixed in a future update.
Either that or do some 2-step workaround similar to this...
Translate
+ with a unique identifier+\s and replace it with some unique identifier, say PLUS_UNIQUEID-\s and replace it with a different unique identifier, say MINUS_UNIQUEIDPLUS_UNIQUEID and replace it with +MINUS_UNIQUEID and replace it with -I reckon the SDLXLIFF toolkit is preferable!

SDLXLFF Toolkit
I had no luck with it because it also replaced the <> brackets of inline tags with their xml counterparts (<, >). Does it always do that?
PLUS_UNIQUEID
The plus isn't really the problem. Eg. replace ([\+\-–])\s(?=\d) with $1 works as well.
Unfortunately it all falls apart as soon as I add the lookbehind.
Here is a sequence that works:
I see you already have the solution, but If there are not many instances to handle, this simple regex in the Find and Replace window and manual replacements will work as well:
([+-])\s(\d)
$1$2
Alternatively, the Search pattern works also in the QA Checker 3.0 > Regular Expressions.
You haven't tried it, have you?
Can you spot the difference? : http://regexstorm.net/tester?p=%28%5b%2b-%5d%29%5cs%28%5cd%29&i=ca+4+%2b+3%2c56+%3d%0d%0a%28%2b+45+%25%29%0d%0aca.+%2b+68%0d%0a6%2b+99+%3d+105&r=%241%242
But you're right, there is a solution in just one go without using lookahead or lookbehind.
I know you are handling exceptions. I just wanted to show a more manual solution.
