Package: libpango1.0-0
Version: 1.28.3-5
Severity: normal
Tags: patch
As reported upstream since Pango 1.24.x in GNOME #583718, Thai SARA AM
(U+0E33) is always rendered with dotted circle in VTE, and thus
gnome-terminal.
https://bugzilla.gnome.org/show_bug.cgi?id=583718
This was once considered a duplicate of GNOME #584160, in which all
complex text languages are to be solved at once. But 2 years have passed
without any progress, and Thai people have suffered and complained
everywhere about this very visible glitch.
https://bugzilla.gnome.org/show_bug.cgi?id=584160
In fact, this problem has been commonly treated in typewriters and
text-mode consoles by letting SARA AM take its own cell without
decomposition, making the fix very trivial. No need for any special
"complex text" analysis.
I have applied the proposed patch in my local repository for Thai users
here, with rebuilding on every update in sid for the past 2 years:
http://ftp.debianclub.org/debclub/pool/main/p/pango1.0/
The patch has even been taken by Thai Ubuntu local team as a solution
for Thai Ubuntu users:
http://www.ubuntuclub.com/node/2970
It should benefit to have the patch merged into sid, to reduce the downstream
difference, until upstream decides something over it.
Regards,
