Description tombil 2012-05-18 11:18:46 UTC

Assume the text of document is "A text text» A text text »text".


When search for:     Result:  
\xBB                 found », OK
\x00BB               not found, WRONG; help says:  format \xXXXX
\x41                 not found, WRONG; should be found "A" 
\x0041               not found, WRONG; should be found "A"

(RegExp is ON; WinXp SP3; OOo 3.4.0 build 9590)

Search with pattern \xXXXX had been OK with OOo3.4.0 beta (build 9583). I have Windows too, therefore do not change fields "Platform".

Comment 2 Regina Henschel 2012-05-20 21:34:23 UTC

The engine for RegEx has been changed to ICU. The syntax is now slightly different. Use \u0041 and switch on "Match case".

The help has to be adapted.

Comment 3 Regina Henschel 2012-05-20 21:47:18 UTC

Please try to use the syntax from http://www.unicode.org/reports/tr18/tr18-13.html.
Please report in a new issue, when something does not work in that syntax.

I'll keep this issue as reminder to update the build help.

Comment 4 tombil 2012-06-11 17:33:08 UTC

The problem is not updating of help.
The main problem is failure backward compatability.
They are macros that use old syntax \xNNNN, as well as the whole branch LibreOffice. If it's feature and not an bug, so it's very unfortunate.
