Sorry for the delay of the answer, but until now had not come into this forum.
You're right lieven23, the problem is the character 'ç' UTF-8 does not interpret.
The solution is simple, edit the file changing the character 'ç' for any other.
I think it is better to have a spelling mistake but the w3c validator validate the code, isn't ?
