# unicode-width

Determine displayed width of `char` and `str` types according to
[Unicode Standard Annex #11][UAX11] rules.

[Documentation](https://unicode-rs.github.io/unicode-width/unicode_width/index.html)

```rust
extern crate unicode_width;

use unicode_width::UnicodeWidthStr;

fn main() {
    let teststr = "Ｈｅｌｌｏ, ｗｏｒｌｄ!";
    let width = UnicodeWidthStr::width(teststr);
    println!("{}", teststr);
    println!("The above string is {} columns wide.", width);
    let width = teststr.width_cjk();
    println!("The above string is {} columns wide (CJK).", width);
}
```

**NOTE:** The computed width values may not match the actual rendered column
width. For example, the woman scientist emoji comprises of a woman emoji, a
zero-width joiner and a microscope emoji.

```rust
extern crate unicode_width;
use unicode_width::UnicodeWidthStr;

fn main() {
    assert_eq!(UnicodeWidthStr::width("👩"), 2); // Woman
    assert_eq!(UnicodeWidthStr::width("🔬"), 2); // Microscope
    assert_eq!(UnicodeWidthStr::width("👩‍🔬"), 4); // Woman scientist
}
```

See [Unicode Standard Annex #11][UAX11] for precise details on what is and isn't
covered by this crate.
