Ok, I thought Braille is limited to 2x3 dots, recently extended to 2x4;
thanks for the explanation!

But those of us who are sighted, are greatly annoyed by characters that are
usually taken for granted being randomly missing. For example, no console
font+mapping shipped with Debian supports âââââ (despite them being a
commonly used part of the BIOS charset), so unless you go out of your way to
beat them back they'll be corrupted (usually into â). Then Perl6 wants ïïâ,
and so on. All these problems would instantly disappear the moment console
sheds the limit of 256/512 glyphs.

So I'm pretty happy seeing this patch set.
