Package: libpango1.0-0
Version: 1.28.3-5
Severity: normal
Tags: patch
As reported upstream since 1.28.0 in GNOME #616495, Lao MAI KONG (U+0EBB)
has been rendered incorrectly in some cases, such as when combined with
PO PA (U+0E9B) or YO YA (U+0EA2).
https://bugzilla.gnome.org/show_bug.cgi?id=616495
This was also reported to Ubuntu in LP #294545, with screenshots, but was
wrongly identified and closed as GTK+:
https://bugs.launchpad.net/bugs/294545
I've just added Pango as an affected project there.
Anyway, the problem still exists in Debian unstable, after all. And, from
the age of the bug, upstream maintainers seem to lose interest in reviewing
my proposed patch (although the initial source in trouble is mine). So far,
I have maintained a patched version after every sid update here for local
Thai/Lao users:
http://ftp.debianclub.org/debclub/pool/main/p/pango1.0/
It should be good to merge the patch into sid, and reduce the difference,
until upstream cares to take it.
Regards,
