I think the Unicode consortium should be taught that full-width and half-width downarrow can be distinguished just as full-width Romaji can be distinguished from half-width Romaji, without even needing CJK. Even a full-width plain blank space is distinguished from a half-width plain blank space.
However, anyone who edits these source files will likely have CJK fonts. The comments are mostly in Japanese. Strings have mostly been moved to data files, but changes to the code are generally accompanied by adding or editing strings that are also Japanese.
Post by Norman DiamondPost by Norman DiamondI do not agree with your statement that downarrow should be displayed as
half-width. It is still

Post by Norman Diamondand UTF-8 does not change the width of the glyph.
The ambiguous width problem have been discussed for a long time.
There is no way to distinguish CJK down arrow and non-CJK down arrow.

If they edit GNOME terminal without CJK fonts, arrows are half-width.
Even if we resolve this Konsole bug, your problem will not be resolved.
You still need to keep in mind that down arrow (and some other characters) have
ambiguous width.
Post by Norman DiamondI do not know who decided that downarrow should have an ambiguous width.
If the Unicode consortium decided that, they're causing problems.

Anyway, let's fix this Konsole's bug.
It is quite difficult to propose a new Unicode specification that can be
acceptable for both CJK and non-CJK people.

Post by Norman DiamondSince the font selection dialog's preview uses Qt widgets instead of
whatever Konsole uses, we
Post by Norman Diamondknow that the full-width downarrow character is displayed as full-width by
these Linux tools.
Post by Norman DiamondFurthermore in Suse 11.0 Konsole itself also displayed the full-width
downarrow character as

not in the rest of

Yes, this is clearly a Japanese specific bug. Could you file a bug

I saw a patch to fix the same problem with emacs about 5 years ago. So
I think this problem can

Post by Norman DiamondKonsole knows that the glyph for 字 is full-width, so Konsole
should know that the glyph for

Down arrow is known as ambiguous-width character. Monospaced font
should provide half-width

full-width down arrow
Post by Norman Diamondfrom a kind of historical reason.
Post by Norman DiamondThe version of Konsole that was included in Suse 11.0 did know
that downarrow is
Post by Norman DiamondPost by Norman Diamondfull-width. I never had to look at what the default font was
because it just worked.
Post by Norman DiamondKonsole's character layouting was changed recently as far as I know
so that some
Post by Norman Diamond(flexible-width) bold fonts can be placed correctly.
I guess it causes this problem.

Maybe, the preview should be removed.

Thank you for the workaround. I will experiment with some
fonts. I would like to

characters so that users can

Post by Fuminobu TAKEYAMAOk, Monospace is an alias of IPAGothic on your environment.
The font, IPAGothic provides double-width down-allow glyph
although Konsole assumes that
'a' and '0'.
