Thanks for the bug report. This bug is due to an overenthusiastic optimization 
that I installed in late 2016. I installed the attached patch to fix the bug.

What I did:
```
grep -Riw cone *
'''

Expected result: lines with the word "cone" surrounded by whitespace, ignoring case.

What I got instead:
```
data/po/pt_BR.po:msgstr "Pressione o ícone de pódio para iniciar o tutorial"
'''

Why this is a bug: the word ícone is not the same as cone and should not have been returned in the result set. It appears that grep treats the í character in ícone as whitespace, which affects other extended-Latin characters as well.
