Description Lawrence Lim 2004-08-30 04:32:20 UTC
Description of problem:
With pango 1.5 in the ja_JP locale, most of the charcters at the end
of each line are truncated. Also, changing the style on the same line,
like in between regular style and bold, there is no spacing between
those glyphs, which is not very ideal.

Downgraded pango on my machine from 1.5 to 1.4 and the difference
between the xchat screenshot varies quite a lot. Please refer to the

Version-Release number of selected component (if applicable):
pango 1.4

How reproducible:

Steps to Reproduce:
1.start xchat in the CJK locale
Actual results:
Characters get truncated.

Expected results:
Similar to pango 1.4 screenshot

This looks rather like a xchat bug, but I'll investigate.

Comment 4 Owen Taylor 2004-09-14 14:55:19 UTC
Actually the vertical and horizontal spacing problems are 

The vertical spacing problem is a Pango bug:


The horizontal spacing problem is an xchat bug (bug 132527)

Comment 5 Alexander Larsson 2004-10-12 12:16:22 UTC
What is the status on the pango problem?

Comment 6 Warren Togami 2004-10-15 04:42:14 UTC
Still problematic in today's rawhide, confirmed in LANG=zh_CN.UTF8

Comment 7 Owen Taylor 2004-10-18 21:51:11 UTC
Should be fixed with pango-1.6.0-4

Comment 9 Lawrence Lim 2004-10-19 02:34:08 UTC
Noticed some of the lines are still not displayed properly. Could you
please verify if this vertical spacing problem (Pango) bug or
horizontal spacing problem (xchat) bug?


Comment 10 Lawrence Lim 2004-10-19 02:35:05 UTC
I was testing with xchat-2.4.0-3, btw. :)

Comment 11 Owen Taylor 2004-10-19 15:20:55 UTC
Is there any reason you would think that was a vertical spacing
problem? The trunctation seems to be all horizontal.

Comment 12 Lawrence Lim 2004-10-20 02:11:16 UTC
OK, I will update bug 132527 then.
