Armin thanks for the clarification.

 From your note, i see what went wrong. We were directly passing pypy's 
UTF-32 (we are testing on linux) to SQLite's UTF-16 API. So this is why 
we only got the first character on the SQLite side.

Also linux's 32 bit wchars are unfortunate in our case, because SQLite 
only supports UTF-8 and UTF-16 in their API. So there is no way on linux 
to directly pass pypy's unicode strings to SQLite.
