md5_hex expects each input character to be a byte (ord = 0..255), whether internally encoded as UTF-8 or not. That's fine.

For simplicity and efficiency, it converts these characters into actual bytes if the internal encoding is UTF-8 using utf8::downgrade or something equivalent.

This means your database or database interface (as used) expects bytes, so it expects your text to be *encoded*.
