This isn't right. A single wide character can take up to four bytes in the utf8
encoding. This works in `CompleteCharacter` as it's only interested in a single
character (and it does the conversion in the other direction). We might be
able get away with overapproximating the size, given that the inputs here
should be fairly small, but adding a loop with partial conversions should not
be that hard either.
