tdf#117643 Writer: fix apostrophe search regression
During text search, ASCII apostrophe ' (U+0027)
of the search term matches the typographic
apostrophe ’ (U+2019) of the text, too.
There was a UX regression in document editing from
commit e6fade1ce133039d28369751b77ac8faff6e40cb
(tdf#38395 enable smart apostrophe replacement by default),
because Find and Replace window and Find toolbar
doesn't replace ASCII apostrophe, so the search term
hadn't matched the text (now with the automatically
replaced typographic apostrophes), as before the commit.
Regex search hasn't been modified, i.e. searching U+2019
is still necessary a search term with U+2019.
The typographic apostrophes of a search term only match
ASCII apostrophes of the text, if the search term contain
also an ASCII apostrophe, too.
Note: as a more sophisticated solution, it's possible to
add a new default transliteration option for this later.
