Description: Upper function does not work
Details:

I have been experiencing some problems with the uppercase
function, when the function has to make simple chars like
'c','a' etc it returns them in uppercase, but when it has to
handle chars like 'á', 'é', 'ç' it does not do so.

For example I have a field named 'med_type' in the table
'test' and one of this data in the field 'med_type' is
'Nutrição'. Then I make the query:

SELECT upper(med_type) FROM test;

It returns:

'NUTRIçãO'

Even changed de characters enconding from UNICODE to ASCII
and the problem still happens.

Is this a bug or am I doing something wrong.

UNICODE is not supported on Win32.
ASCII does not know how to handle those characters.

You need to pick the correct encoding for these characters. Make sure you set the correct locale as well.

Also, you really should upgrade to the release version.
