Thank you for looking into this part of pypy's performance. Whenever
something reaches a testable state we would be glad to test/benchmark it.
On another front. We tried using SQLite's UTF-16 API to avoid doing the
conversion to UTF-8 whenever we returned a string from pypy to SQLite. We
used function "sqlite3_result_text16":
http://www.sqlite.org/c3ref/result_blob.html
defining it in CFFI as:
void sqlite3_result_text16(sqlite3_context*, wchar_t*, int, void(*)(void*));
The problem was that giving directly a pypy string to above function (using
wchar_t type), only the first character of the string was passed to SQLite.
The only way to successfully pass a string to SQLite was by explicitly
converting/encoding it to utf-16.
So the question i have is, does pypy keep its strings internally to utf-16?
Thanks again (and a happy new year) to all.

Are you talking about strings or unicodes? that is, type str or unicode?
For unicode only. For regular type == str we use SQLite's
sqlite3_result_text without doing any conversion/encoding at all.
