--- Comment #5 from V Stuart Foote <vsfo...@libreoffice.org> ---
Unicode BIDI handling provided by ICU lib are already implemented but depend on
the RTL/LTR direction assignment for a text run or full paragraph. Assignments
are currently done in UI as direct formatting applied from UNO button actions
on the Standard Toolbar. And automated against text runs of Unicode with
"Strong" bidi values. Some recent adjustments [1][2][3]
So the issue is language detection of text runs, words, sentences, and
paragraph blocks. And automating PS assignment as RTL/LTR is similar to
language detection/assignment needs for Spell checking, i.e. bug 91766.
Additionally language could be assigned based on IME or keyboard locale
detected. But we have issues with those approaches, bug 113298.
Once language detection improves, our "Complex" 'CTL' classification and
RTL/LTR formatting can follow with it, and we can assign/format direction.
