Hi Oscar,

Thanks for explaining the caching in detail :-)

Actually, you need to walk the string even to do "u =
s.decode('utf-8')".  The reason is that you need to check if the byte
string is well-formed UTF-8 or not.  So we can build the cache eagerly
in all cases, it seems.


A bientôt,

Armin.
