char type is 32-bits in size.
Rust by Example: Strings
A String is stored as a vector of bytes (Vec(lt;u8>), but guaranteed to always be a valid UTF-8 sequence. String is heap allocated, growable and not null terminated. &str is a slice (&[u8]) that always points to a valid UTF-8 sequence, and can be used to view into a String, just like &[T] is a view into Vec<T>.
There are several crates on crates.io which offer Unicode normalization.
Rust strings have the function
as_bytes() which returns a
byte slice of the stringss contents.
An array of
u8 (presumably of UTF-8 bytes) can be converted to a
There are several crates on crates.io which offer conversion to IDN.
