Thread: Problem with upper function and special characters

Hi,

I don't believe that locale is supported in postgresql.

See http://www.postgresql.org/docs/7.4/static/multibyte.html#AEN18181
for a list of supported character sets.

Double check and make sure that postgres didn't use the default encoding
of Unicode instead.  There is a known bug in 7.4x with Upper/Lower
conversion in Unicode and perhaps that is affecting your encoding as
well.
