# Unicode Language
This library detects language support given a list of Unicode codepoints. This is primarily useful for finding out what languages a font supports.
```rust
// Input codepoints as a vector of Unicode ranges
let codepoints = vec![[65, 121]];
// Detect languages with a threshold of 0.5
let results = detect(codepoints, 0.5);
// results[0].tag = "en"
// results[1].tag = "nl"
// ...
```
The result is a vector of `Match` structs, with the following signature:
```rust
struct Match {
// BCP 47 language tag.
tag: &'static str,
// English name.
name: &'static str,
// Name in native script.
native: &'static str,
// Number of codepoints matched.
count: u32,
// Score (number of codepoints matched divided by the total).
score: f64,
}
```
The language data is derived from [Adobe Font's speakeasy library](https://github.com/typekit/speakeasy). The data is extracted at build time and statically compiled as part of the library.
