When using templates, and we need to use character which are not included in the ASCII character set, like the Spanish accentuated characters, Djanfgo must be informed about such a thing in order to properly handle these characters.
To this end, we need add the following at the first or sencond line of code of the Django source code file:
# coding: utf-8
This will allow rendering Spanish characters like te following, without any problem:
á é í ó ú ü ñ Á É Í Ó Ú Ñ
Here is a good place to start and further understand what we have so far explained here: Defining Python Source Code Encodings
