There's a bizarre font bug in both #unscii and #funscii that I have fixed locally and have to push out. Half of the uppercase letters in one of the 8-bit fonts are off by one code point.

I spotted this when my Z shell prompt changed to "JdeBQ".

It does mean that that font is missing a letter. I tried to look for an authoritative original source to fill it in from, but couldn't find one.
