--- Comment #3 from Khaled Hosny <[email protected]> ---
After a bit of debugging I think I found the root of this. Basically characters
from Combining Diacritical Marks block are classified as ScriptType::LATIN when
they should have been ScriptType::WEAK. This comes from
i18npool/source/breakiterator/breakiteratorImpl.cxx:
BreakIteratorImpl::getScriptClass() which calls
getCompatibilityScriptClassByBlock() which in turn checks the scriptList array
that assigns all blocks from UBLOCK_BASIC_LATIN to UBLOCK_ARMENIAN as
ScriptType::LATIN and this includes UBLOCK_COMBINING_DIACRITICAL_MARKS.
This comes from
https://gerrit.libreoffice.org/gitweb?p=core.git;a=commitdiff;h=bf355b97ee4b53e38975f0e1847eda5b3e05f920
to fix bug 38095. I don’t know what old classification was and whether it
indeed classified combining marks as Latin, but either way it does not make
terrible since.
If I modify scriptList to skip UBLOCK_COMBINING_DIACRITICAL_MARKS, then I get
correct rendering here.
