MetaFun is based on Context, right? Unfortunatly I have no experience
with it.

I was able to include the figures using the above as an example. But I
do not know how to get my labels with correctly accented letters (like
á, ã) and cedilla (ç). If it was latex, that this would be no
problem. How can I get those gliphs in MetaFun?
