Pango not placing diacritics (24.01 KB, image/png)
2005-11-23 14:18 UTC, Denis Jacquerye 		Details

Description Denis Jacquerye 2005-11-23 14:08:24 UTC 
If a font does not have OpenType GPOS and GSUB table defining where the
diacritics should go, they just end up in the same position everytime.
Independently of which characters they are composed with.

Instead they should either stack upwards or downwards, for above diacritics and
below diacritics. Qt does something like this. Pango should be able to
heuristically place diacritics.
Comment 1 Denis Jacquerye 2005-11-23 14:16:49 UTC 
There is relevant discussion in the report for Bug 101079.

Here are the relevant examples using the Gentium font from SIL:
* Qt placing diacritics without the help of OpenType : attachment 54465 [details].
* UTF8 file being used : attachment 32984 [details]

* Pango not placing diacritics when the font doesn't use OpenType feature for
them
