It uses 0xc0, 0xaf. Now, in utf-8, that's an nonconforming sequence. "The Unicode and UCS standards require that producers of UTF-8 shall use the shortest form possible, for example, producing a two-byte sequence with first byte 0xc0 is nonconforming. Unicode 3.1 has added the requirement that conforming programs must not accept non-shortest forms in their input." So is it that exfat is rejecting nonconforming sequences? Or is it converting the nonconforming sequence from 0xc0 0xaf to the conforming sequence 0x2f, and then rejecting it (because it's '/')?
