Which terminal? I see no artefacts in konsole, so it's more likely a
bug in the terminal you use.

Neither do I in PuTTY, which emulates xterm.
Richard, if you disable auto-composition-mode, does that help?

I am using a Linux terminal.
Emacs needs to cope with it, unless we can get it fixed.

The bug does not happen when auto-composition-mode is disabled.

Emacs cannot know how characters are drawn on a tty.

Does that mean you understood what causes Richard's problem? If so,
can you explain?
I thought asking Richard for dribble files in both cases, but if you
already understand what's going on, there would be no need.
I actually don't understand why we have auto-composition-mode turned
on for TTY frames, and where do we take the data for composing
characters there (there's no font back-end). Kenichi, can you
explain, please?
Thanks.

The terminal has to support composition. The Linux console doesn't.

Ah, I see, thanks.
So maybe we should only turn on auto-composition-mode in
terminal-specific files like term/xterm.el?

It can, and it does -- with the help of termcap.

I sent a very simple reproducible test case -- better than a dribble
file. Did you mean a termscript file?

I don't see the problem on fencepost accessed via PuTTY.

Yes, sorry. But now that Andreas explained the problem, there's no
need.
