pub fn encode_utf32<I: IntoIterator<Item = char>>(
    iter: I,
) -> EncodeUtf32<I::IntoIter> ⓘExpand description
Creates an iterator that encodes an iterator over chars into UTF-32 u32 values.
This iterator is a simple type cast from char to u32, as any sequence of chars is
valid UTF-32.
§Examples
use widestring::encode_utf32;
let encoded: Vec<u32> = encode_utf32("𝄞music".chars()).collect();
let v = [
    0x1D11E, 0x006d, 0x0075, 0x0073, 0x0069, 0x0063,
];
assert_eq!(encoded, v);
