Comment 3 Leon Ho 2004-07-13 03:22:15 UTC

I have debugged for a while and found out because when it itemize and
shape, it returns a GList of PangoGlyphString (glyphs) and Glist of
PangoItem (items) to draw_text()

Because the nature of Indic scripts that several characters can be
represent as a glyph, so the PangoItem and PangoGlyphString does not
align together.

PangoItem        [1] [2] [3] [4] [5]
PangoGlyphString [1]         [2] [3]

But gtkhtml still access PangoItem one by one (There aren't any ways
to know how many chars the glyph represent) hence the attribute used
in indic glyph are used on english glyph.

I recommend we close this bug, since hindi + english works fine now as
per the screenshot attached above.
This is with evolution 1.5.94.1-1 and gtkhtml3-3.3.0-3 on RHEL4 B1
from 16.09.04.

Comment 8 Leon Ho 2004-09-23 12:22:09 UTC

Double that. It is looking fine. Closing this bug for now.
