hashcat wiki has mangled this one, replacing what I think was the
double-quote character and the three characters less-than, equal, and
greater-than with some UTF-8 stuff. Here's what I think what was meant,
represented via ASCII codes:
21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 3a
3b 3c 3d 3e 3f 40 5b 5c 5d 5e 5f 60 7b 7c 7d 7e
This is 32 chars.

This gives us 94 chars, so it's simply the whole range from 0x21 to 0x7e.
Note that it does not include the space character (0x20), which I think
was a bad idea. Should we define our ?a to include the space character
as well? (hashcat may then choose to redefine their ?a in a similar way
or not.) Or should we use e.g. ?A to mean "really all printable ASCII,
including the space"?

Yes, they are. I think we can implement ?h, but initially omit the rest.
While German and French probably assume iso-8859-1, it is unclear to me
(without testing) which 8-bit charset is assumed for Russian, since
there are several of them in use.
