Hi,

Package: openoffice.org
Version: 1:3.2.1-5
Severity: normal


There is a problem rendering some glyphs  of Malayalam language.

Glyph reordering and substitution  with some (not all) glyphs is
not happening.

This is a fresh install of 32 bit OO.o; I used to have a 64 bit
OO.o till 10 days back, this problem was not there. I am nut
sure if some thing has changed in 10 days.

I assume ttf-malayalam-fonts are installed.

I am attaching a sample html file, and the difference
would be  apparent if the text is viewd in both iceweasel
or iceape (prefered - not sure how it renders in other
browsers - certainly will not render properly in text only
browsers) and any of OO.o components.

See the screenshot attached. On left is the html rendered in
iceape - correct rendering; and right side is the rendering
in OO.o word. (wrong rendering).

The problem is existing in at least spreadsheet too.

Have not checked other components.

Problem seems to be with icu or whatever equivalent of pango used by
OO.o for text rendering / layout.

Do you have any idea here? Further informations/observations of him:
- works with amd64, i386 fails
- version built against ICU 4.2 seems to work, the one with ICU 4.4 not.

René

Harfbuzz looked hopeful as a unified place for icu/pango/etc to put the
reordering rules, but they're still basically stubbed out there.

I do have on my own to-do list to attempt the above Malayalam rules for
ICU, but its thankless work so I've continually punted it out too the
future.

Last month there was an related discussion on the OpenType list ("Left  
Matra Reordering Question") and in the end the core developer of ICU's  
layout engine claimed that he now knows how to make the everything work.

There are good chances that the latest ICU trunk already works...
