That seems somewhat of a premature optimization.  Dicts are very 
efficient -- I don't imagine 100k+ entries will slow it down, but then 
that's what should be tested so you'll know.

Like this?

 >>> print repr(''.join(chr(ii) for ii in range(20,40)))
'\x14\x15\x16\x17\x18\x19\x1a\x1b\x1c\x1d\x1e\x1f !"#$%&\''
