Since the font selection dialog's preview uses Qt widgets instead of whatever Konsole uses, we know that the full-width downarrow character is displayed as full-width by these Linux tools. Furthermore in Suse 11.0 Konsole itself also displayed the full-width downarrow character as full-width. So I think this bug is in the newer version of Konsole itself, not in the rest of Linux. I can't say if the preview window should be removed because it doesn't really provide a preview, but it helped narrow down this bug. I do not agree with your statement that downarrow should be displayed as half-width. It is still the same character that it used to be in ShiftJIS and EUC encodings, and the adoption of Unicode and UTF-8 does not change the width of the glyph. If I the character becomes half-width when I edit source files in Konsole, but it's still full-width when other people edit the same source files in a Gnome terminal or even in Windows, it will result in people scrambling source files. Full-width a and half-width a do not have ambiguous widths. Full-width ア and half-width ア do not have ambiguous widths. I do not know who decided that downarrow should have an ambiguous width. If the Unicode consortium decided that, they're causing problems.
