typing in non-utf8 causes panic

[cmsd2]

this is on the new linenoise-ng code:

tried typing in some non-utf8 garbage.
predictably it panics at
let cast = str::from_utf8(CStr::from_ptr(ptr).to_bytes()).unwrap().to_string();
around src/lib.rs:79

not sure what the correct response is. print the error and return None?
change the signature to return a Result<Option> ?

Were you using a special environment/locale? Or were you just trying to break by pasting random bytes in the console?

• I can either losely convert to utf-8
• Or try to inspect the environment to find the encoding and use the encoding create to perform the decoding
• Do nothing and support only utf-8
