Unicode problem

[Jaimerson Leandro Amaro de Araújo]

Hello, I'm stuck in a encoding issue, on the dashboard template. Some of my models have fields with non-ascii characters (like "à" or "á"), and when I try to load the page, I get the following error:

DjangoUnicodeDecodeError at /

'ascii' codec can't decode byte 0xc3 in position 5: ordinal not in range(128).
You passed in <django.utils.functional.__proxy__ object at 0xb581d98c> (<class 'django.utils.functional.__proxy__'>)

[...]

Unicode error hint

The string that could not be encoded/decoded was: Conte��do

Please, advise.
