Comment (by teor):

 If C doesn't reject bad UTF-8, and Rust does, then that's a potential
 difference in behaviour.

 We could avoid this issue by making both C and Rust check that all
 directory documents are ASCII (#18938), or that they are all UTF-8. We
 have a proposal for making directory documents UTF-8.
