Thank you so much, that means a lot! Missing accents were exactly the problem I wanted to solve, so it's great to hear it from someone who deals with it every day.
PT-BR should be fully covered (ã, õ, ç, â, ê, ô, á, é, í, ó, ú, à...), but a real-world test is always better than my own checks. If you ever try the fonts in a project and spot anything odd, I'd love to hear about it.
I'll keep your offer in mind for translation too. Thanks again, and good luck with your projects!
