Bug 208511

Created attachment 141191 [details]
texinfo test file

I think I have reproduced this.  Essentially, what is happening is the
standalone info is splitting up multibyte characters when the terminal window is
resized.

I should correct you here: the CJK character takes three times the width of an
ASCII character.  But anyway, your point is still true: I have reproduced this
problem.  However, the bug is reported against the wrong component: the emacs
packages do not supply the standalone info program, so I am going to reassign
this bug to the texinfo maintainer.

If I'm not wrong there is no utf8 support in info. I don't
even understand why some multibyte characters appear rightly.

The above patches have all been submitted upstream, and handle everything but
input of multibyte characters in the info modeline (e.g. searching for
multibyte characters).

Is it fixed, or not?

No, it is not. Patches sent to upstream by Miloslav, but still not included in
4.11. But it should be fixed in 4.12 (see Changelog), so I will check it after
update to 4.12 in Rawhide.

Changing version to '9' as part of upcoming Fedora 9 GA.

I tested 4.12 version... it still doesn't work:(

Fixed in texinfo-4.13-1.
