unicode-normalization

Unicode character composition and decomposition utilities as described in Unicode Standard Annex #15.

This crate requires Rust 1.36+.

extern crate unicode_normalization;

use unicode_normalization::char::compose;
use unicode_normalization::UnicodeNormalization;

fn main() {
    assert_eq!(compose('A','\u{30a}'), Some('Å'));

    let s = "ÅΩ";
    let c = s.nfc().collect::<String>();
    assert_eq!(c, "ÅΩ");
}

crates.io

You can use this package in your project by adding the following to your Cargo.toml:

[dependencies]
unicode-normalization = "0.1.24"

no_std + alloc support

This crate is completely no_std + alloc compatible. This can be enabled by disabling the std feature, i.e. specifying default-features = false for this crate on your Cargo.toml.

Note about MSRV

Dependencies' MSRVs evolve independently of this crate's MSRV. Old versions of cargo will always try to get the most recent versions of the dependencies. Therefore, if you are having troubles compiling on an old Rust version, try to install an older version of the incompatible dependency.

For instance, to compile on Rust 1.36, tinyvec must be <=1.6.0

cargo update -p tinyvec --precise 1.6.0
