Hello, I have a question regarding Noesis. Is there a need to adjust or configure anything in Noesis to properly handle accents such as "ã, ç, é, á," and others? I'm currently working with C++.

Hello, you just need to use a font that provides that kind of glyphs.
In the application framework we specify a list of fallback fonts for each platform (SetThemeProviders) that usually covers all kind of languages.

Also in C++, make sure you are using UTF-8 encoded strings and save your XAMLs in UTF8 mode.
