cargo --help`printf "\\x8d00"`
panics, because "did you mean?" tries to use the arg with an invalid codepoint. It's an invalid user input, not a programmer bug, so IMHO it shouldn't cause a panic.
This fix uses
to_string_lossy
, so this case displays as:Since that's an error case, the lossiness shouldn't be an issue, and the correction is still useful.
