Thread: upper() with LATIN1 problem

upper() with LATIN1 problem

From

Hi,

The developers on my company reports me a problem with de upper() function.

The problem is:
- with a text 'magriñá'
- the upper('magriñá') returns MAGRIñà
- NOTE that the characters 'ñ' and 'á' didn't change the case.
- the text are stored in a table in a character varying(50) field
- the database has LATIN1 encoding
- the postgresql version is 7.4.7
- the OS is Debian Linux 2.6.10

Please, can anyone help me to resolve this problem?

Thanks!

This is determined by your locale (specifically LC_CTYPE) not by what
the database thinks the encoding is.  You'll probably want to re-initdb
in the desired locale.

Hi,

I look at the variable/parameter LC_CTYPE and it is set to C (I think
this is the default) for performance reason, the installer says.

If I use LATIN1 (spanish) what value is the best option for this
variable/parameter?

Thanks!

Unfortunately locale names are not all that well standardized.
"locale -a" should show you all the names available on your platform.
You probably want some variant of "es_ES", the tricky part is figuring
out which one uses LATIN1 as opposed to any other encoding.
