This shows that if it's a valid character in the current locale, bash will
convert it and read it back. `printf' takes the unicode encoding (in this
case, a three-byte character) and runs it through iconv to try and convert
it to a valid multibyte character in the current locale.

It's apparently not a single character in that locale.
