grep/regex can't find accented word

Question

I\'m trying mount a regex that get some words on a file where all letters of this word match with a word pattern.

My problem is, the regex can\'t find accented words

Answer 1

Assuming everything is UTF-8, I’d usually just use something like

perl -CSAD -le 'print if /^carroça{1,3}$/' filenames

because then I know what it’s doing.
