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)
