--- Comment #7 from Eike Rathke <[email protected]> ---
Help needs to be updated.. The ICU regular expressions are slightly different
in details from the home-brewed OOo expressions, for this example the four hex
digits following the \x are not accepted, \x accepts only two hex digits for
values <=255, so \xhh. More hex digits (1-6) are accepted in the form
\x{hhhhhh}. These two forms are actually identical with Perl regular
expressions. As an ICU Unicode extension also the form \uhhhh with exactly four
hex digits can be used, or \Uhhhhhh with exactly six hex digits. For more
details see the mentioned metacharacters URL
http://userguide.icu-project.org/strings/regexp#TOC-Regular-Expression-Metacharacters

For the \xAD that according to comment 4 does not work I'm not sure, is a
soft-hyphen even part of the text? Isn't it only generated by word breaking?
Does \u00AD find it? On the other hand I spotted some special treatment of
0x00AD in sw/source/core/crsr/findtxt.cxx SwPaM::DoSearch() that for if
bRegSearch is supposed to set bRemoveSoftHyphens = false;
