Обсуждение: lower does not handle german umlaut

If I perform a select lower() on uppercased german umlauts, these wont be
converted to lowercase. Is this a bug or a feature or did I just miss
some settings ?

thnx,
peter

AFAIK this should work if (a) the system was built with --enable-locale
and (b) you are running it in an appropriate locale setting.  The
SQL lower() function just invokes the C library's tolower() conversion
routine, so if it doesn't work your beef is with tolower() ...

try select to_ascii()

I use it for French
