Should I avoid accents when coding?

Question

English is not my native language. So when I do some projects, sometimes I use some portuguese words to define methods, variable names, comments...
The problem is when I push to GitLab, for instance, my code are not displayed properly. If I use some library, sometimes I get a runtime error, because an accent is not interpreted by the library... So these problems I get because somethings doesn't support Unicode chars.
So, should I change my code, avoiding accents?

Answer 1

Yes, it's more safe to use only non accentued letters: even if unicode is from more to more supported, it could always be source of problem when sharing files ^^
