Well, my medication has finally worn off, and I came up with this:
a_string.tr('^ -~', ' ') Any comments on efficiency?
God bless ascii for being contiguous. All this is to clean up
imperfectly mapped EBCDIC (eeeww!)
Thanks for the suggestions.

It looks to me like this is a solution for a different problem;
that is, discarding characters outside of the specified range.
Also, do we want to map newlines, etc? Anyway, irb sez:
Oops, I misread that. Yeah, gsub is probably faster.
string.unpack('U*').map { |c| (0x20..0x7e).include?(c) ? c :
32 }.pack('U*')
Anyway, just throwing out characters doesn't seem like a likely use-
case anyway.
