13extern crate unicode_width;
14
15use unicode_width::UnicodeWidthStr;
16
17fn main() {
18 let teststr = "Ｈｅｌｌｏ, ｗｏｒｌｄ!";
19 let width = UnicodeWidthStr::width(teststr);
20 println!("{}", teststr);
21 println!("The above string is {} columns wide.", width);
22 let width = teststr.width_cjk();
23 println!("The above string is {} columns wide (CJK).", width);
24}
25```

27**NOTE:** The computed width values may not match the actual rendered column
28width. For example, the woman scientist emoji comprises of a woman emoji, a
29zero-width joiner and a microscope emoji.

31```rust
32extern crate unicode_width;
33use unicode_width::UnicodeWidthStr;
34
35fn main() {
36 assert_eq!(UnicodeWidthStr::width("��"), 2); // Woman
37 assert_eq!(UnicodeWidthStr::width("��"), 2); // Microscope
38 assert_eq!(UnicodeWidthStr::width("����"), 4); // Woman scientist
39}
