Is the word feios the same in Brazilian and European Portuguese?

Yes

The word "feios" is identical in spelling, meaning, and grammar in both Brazilian and Continental Portuguese. The only differences are phonetic:

• Vowels: In Brazilian Portuguese, the "e" is often more open ([ɛ]), whereas in Continental Portuguese, it is typically more closed or even reduced ([e] or [ɨ]).
• Sibilance: In many Brazilian dialects (such as in Rio de Janeiro), the "s" at the end of the word may sound like "sh" ([ʃ]), while in others (such as in São Paulo), it remains a dental [s]. In Continental Portuguese, the "s" is almost always pronounced as a "sh" sound ([ʃ]).
