Byte container optionally encoded as UTF-8. It is intended as a byte sequence type with uncertain character encoding, while the caller might be able to determine the actual encoding.
For example, ZIP file format
originally didn't support UTF-8 file names,
assuming the archive would be extracted only in the system
with the same system encoding as the original system.
The newer ZIP standard supports explicitly UTF-8-encoded file names though.
In this case, the ZIP library may want to return either a String or Vec<u8>
depending on the UTF-8 flag.
MaybeUTF8 type supports various conversion methods.
For example, if you know that the bytes are encoded in ISO 8859-2,
Encoding can be used to convert them:
```rust extern crate encoding; use std::borrow::IntoCow; use encoding::{Encoding, DecoderTrap}; use encoding::all::ISO88592;
let namebuf = MaybeUTF8::fromvec(vec![99,97,102,233]); let name = namebuf.mapintostr(|v| ISO88592.decode(&*v, DecoderTrap::Replace).unwrap()); asserteq!(name, "caf\u{e9}"); ```
