grep uses plain char and doesn't support UTF-8. But if your "héhé"
fits in an 8-bit code page, and you have the proper LC_CTYPE set, it
works. I checked this with cp1251 "боза" earlier when we discussed
word finding (but was 99% sure it'll work).

echo '@@боза@@' | grep -w '@боза@' works too, but echo 'а@боза@@' does
not, and neither does '9 at ...' or '_ at ...' . So it checks the characters
before and after the match for not being isalnum() or underscore.
