diff: do not split function name if character encoding is unknown

Only ASCII characters can be split reliably at any byte positions, so let's
just leave long multi-byte sequence long. It's probably less bad than putting
an invalid byte sequence into a diff.

This doesn't try to split the first ASCII slice from multi-byte sequence
because a combining character may follow.
