Write Unicode str as utf-8

[kent sin]

Python support unicode, but some library don't. Write
is one of them. 

When writing a csv file, The rows contains numbers and
unicode str. It is a little pain to first convert all
unicode str to utf-8 before writing the row.

Are there anyway I can patch python such that It will
convert the unicode string to utf-8 before the write?
Where should I start?
