tdf#104597 related: restore the mirroring of Bidi_Mirrored characters
The method PDFIProcessor::mirrorString() was removed, and
::comphelper::string::reverseString was used, by Kevin Suo in commit
69e9925ded584113e52f84ef0ed7c224079fa061.
The old PDFIProcessor::mirrorString() did two things:
1) Reverse the code points in the string. However, due to its use of iterateCodePoints(&i)
rather than iterateCodePoints(&i, -1) (i.e. iterating in forward rather than reversed order),
the reverse was not functioning at all.
2) Use GetMirroredChar (i.e. the icu unicode u_charMirror() which was dropped in
commit 720a093461aadff044ac0b1b7b45cf3d416b3785) to get the mirrored-image of
characters with the Bidi_Mirrored properties.
Stephan Bergmann restored the #1 in commit 50d73574b6c3d71f9a539c895a15d6fcda22390b
(by introducing comphelper::string::reverseCodePoints). However, the #2 was not restored.
I do not see a clear reason to drop #2 (at least this is an area I don't quite familiar
with), so it's better to restore it as well, in *this* commit, named as SubstituteBidiMirrored.
