Thank you! Quite frankly, I didn't know about ordinals *blushes*.
Also, I thought that d.update({k: v}) was equivalent to d[k] = v, but
apparently it's not. So thank you twice!
Cheers!!

Perhaps the doc should be more obvious and perhaps unicode.translate is badly
designed, but:
translate(...)
S.translate(table) -> unicode
Return a copy of the string S, where all characters have been mapped
through the given translation table, which must be a mapping of
Unicode ordinals to Unicode ordinals, Unicode strings or None.
Unmapped characters are left untouched. Characters mapped to None
are deleted.
it says "mapping of Unicode ordinals to Unicode ordinals, Unicode strings or
None"
which reads as a mapping of (int) to (int, unicode, or None).
your translation table is a mapping of (unicode) to (str).
this works:
for f, a in zip(funnychars, asciichars):
trans.update({ord(f): unicode(a)})
this as well:
for f, a in zip(funnychars, asciichars):
trans.update({ord(f): ord(a)})
btw, you're updating the dict and creates a new dict for each character then
immediately disposing it. Why not just:
for f, a in zip(funnychars, asciichars):
trans[ord(f)] = ord(a)
