I analyzed the problem and developed the both proof-of-concept workaround
above. The reasons that
the first patch works seems to be that
- GraphiteServerLayout returns a char_index that is off by mnMinCharPos
(relative to text_ptr)?
- PrinterGfx uses these unicode codepoints somehow for caching?
- and gets confused by different unicode->glyph mappings?
This raises some important questions though. With CTL text having non-1:1
unicode->glyph
mappings and non-trivial glyphidx->stringidx mappings being quite common if
there is a dependency
in PrinterGfx on other assumptions then we have a problem.
Why are the unicode codepoints used anyway when perfectly fine glyph indices
are available? The
second workaround is more more radical and patches out the reverse mapping into
the string
altogether. It seems to work too...
Other than that the GraphiteServerLayout should behave similarly to the other
Layouts regarding the
returned char positions.
