```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);
|
||
}
|
||
```

|
||

||
