In Belgium, we use the character ë.
But when I use this character in an app, I get an ansii error.
How can I solve that?
In Python 2, you need to specify the encoding of each file. This just means putting the following at the top of each file:
# coding: utf8
Then, if you want to use a character in a string, put a
ucharacter before the quote, e.g.
screen.text(u'In Belgium, we use the character ë.')
ucharacter tells Python that this string is a 'unicode' string, which is a different type from the normal strings.
