And if they haven't purged support for ancient encodings, that support is thoroughly bitrotten. Thus, I disagree that this is a legitimate concern. What _could_ be a legitimate reason is that someone is on a _terminal_ that can't display a wide enough set of glyphs. Such terminals are: ? Linux console (because of vgacon limitations; patchsets to improve other cons haven't been mainlined) ? some Windows terminals (putty, old Windows console) that can't borrow glyphs from other fonts like fontconfig can For the former, it's whatever your distribution ships in /usr/share/consolefonts/ or an equivalent, which is based on historic ISO-8859 and VT100 traditions. For the latter, the near-guaranteed character set is WGL4. Thus, at least two of your choices seem to disagree with the above: [dropped] > 0xd7 => 'x', # MULTIPLICATION SIGN [retained] > - U+2b0d ('?'): UP DOWN BLACK ARROW ? is present in ISO-8859, V100, WGL4; I've found no font in /usr/share/consolefonts/ on my Debian unstable box that lacks this character. ? is not found in any of the above. You might want to at least convert it to ? which is at least present in WGL4, and thus likely to be supported in fonts heeding Windows/Mac/OpenType recommendations. That still won't make it work on VT. Meow! -- ??????? .--[ Makefile ] ??????? # beware of races ??????? all: pillage burn ??????? `----
