cannot replace when regex in find field

Question

Hi there, I have a lot of this in my target: 620x260x440mm (24.4 x10.2x17.3in) Some have no space others have U00A0, U2000 or what so ever following the numbers. I would like to replace all instances of number + unit/x with number+U202F+unit/x. So I press Ctrl+H and I enter the following expression into the find field: ( ? < = \ d ) \ p {Zs}* ( ? = [xmi] ) I check the case sensitive and regex boxes and find nicely all I want. Now the promblem: I cannot replace it with my U202F nor with anything else. Whenever there is a regex in the find field, the replace field seems not to work anymore. Why is that? Ideas anybody? I use Studio 2015 Freelance and the source is a docx, that I got as a package. Thanks in advance! Uta 
 PS: I posted this question already in ProZ, but no one answered...

About your first regex, it's the same with my Studio 2014: Studio matches but can't replace even if the Replace wit h field is as simple as foo. (BTW: there are extra espaces and \ in your regex). 
 About your second regex, I'd say it's the expected behaviour, nothing buggy here. 
 
 Maybe you can divide the solution in 2 regexes: 
 (1/2) This regex will match the X'es: 
 Find what: (\p{Zs}*)(x)(\p{Zs}*) 
 Replace with: &deg;$2&deg; 
 where &deg; is the non-breakable space 
 
 (2/2) This regex will match the in's and mm's 
 Find what: (\d)(\p{Zs}*)([mi]) 
 or 
 Find what: (\d)(\p{Zs}*)(mm|in) 
 Replace with: $1&deg;$3 
 where &deg; is the non-breakable space 
 Anyway, I'd recommend you too the Regex Match Solution Provider (find it here: http://appstore.sdl.com/app/regex-match-autosuggest-provider/412/ ): You would be able to translate on the fly (which is easier and automatic), not replacing after translation. 
 
 Hope it helps.
