Weird characters in v3.0.0

I install the 3.0.0 version and found weird characters on UI. My language and system is portuguese. How I can solve this? There’s some screenshots:

Update. I read something about Latin Fonts and change fonts on: File > Options > Appearance > General Interface > GUI Font > Menus and Window Font to Arial 9.

But there’s some places, like on software fields (see attachment) that weird characters appears. Sometimes i cannot understand what is going. There’s another place where I can change Font Configuration and make it work?
