Using Django Mystery Errors

Hi, I have a problem with utf-8 encoding.

When I load models in admin page i get

Internal Server Error: "<MY_ENDPOINT>"
Traceback (most recent call last):

UnicodeEncodeError: 'ascii' codec can't encode character '\xf6' in position 69: ordinal not in range(128)

File name that contains åäö is some migrations files.

I run ubuntu server with apache2.

When I load same models in normal views it works and url with åäö works to.

It works when i run dev env with production DB.

I have set AddDefaultCharset UTF-8 in apache2
Ubuntu locale --> LANG=sv_SE.UTF-8...

in settings.py

DEFAULT_CHARSET = 'utf-8'
FILE_CHARSET = 'utf-8

I dont understand why self.engine.file_charset == ascii?
Why can’t django/apache read utf8 chars in file name?
Why can windows/manage.py runserver handle the utf8 file names?
Why do I only get this in the admin page?

Finally found the problem.

I can’t answer why the app works as normal if I don’t use the admin page.
My guess is that the admin page read files a bit different.
Now, however, the admin page loads all the models as well.

In /etc/apache2/envvars :
From

## The locale used by some modules like mod_dav
export LANG=C
## Uncomment the following line to use the system default locale instead:
#. /etc/default/locale

export LANG

To

## The locale used by some modules like mod_dav
#export LANG=C
## Uncomment the following line to use the system default locale instead:
. /etc/default/locale

export LANG
