Description mixmaxtw 2007-04-24 09:59:07 UTC

For some languages, combining diacritics must be used to compose the necessary
glyphs. For this, some OTF/TTF fonts come with entries in the GPOS and GSUB
tables to specify where exactly on the base glyph should be the diacritic
attached. Fonts like Dejavu Sans and SIL Doulos support these needed features.
Now the rendering engine needs to support this feature too to correctly render
the base glyph and the diacritic(s). OpenOffice.org in Version 2.2.0 lacks this
support, so the rendering will be ugly, because it merely centers the diacritics
on top of the base glyph, but this does not always fit.

To test this issue, please see the Test files for Amis, Paiwan and Tsou
languages on http://i18n.debian.net/wiki/TaiwanAboriginalLanguages
Open the text files in OO.o and view them with either the Dejavu Sans or the SIL
Doulos font.
