           Summary: Opentype Latin fonts poorly handled
           Product: Ubuntu
           Version: unspecified
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: libpango1.0-0
        AssignedTo: seb128 at ubuntu.com

We need correct opentype support for latin script based African languages to be
able to translate and have the characters displayed properly.

1. There's a lack of fonts with proper OpenType definition for characters and
diacritics.
2. Even if a font has that support (I only know 1 or 2) it is not rendered
correctly at all. The mark, mkmk and liga tags are unused.

Example : type A + "U+0300". Either the font should merge this into a ligature À
or use the mark anchor to place the accents on top of the A instead of over it.

See http://bugzilla.gnome.org/show_bug.cgi?id=101079 for proposed patch that
needs work.

There should be an evaluation of the latin fonts, to know which are included by
default in Ubuntu. It's sort of useless having characters if they aren't handled
properly, we might as well not use them, but we need them to type in some languages.
