# Unicode Text Segmentation for Go
|
||||
|
||||
[](https://godoc.org/github.com/rivo/uniseg)
|

|
||||
|
||||
This Go package implements Unicode Text Segmentation according to [Unicode Standard Annex #29](http://unicode.org/reports/tr29/) (Unicode version 12.0.0).
|
||||
|
||||
At this point, only the determination of grapheme cluster boundaries is implemented.
|
||||
|
||||
## Background
|
||||
|
||||
In Go, [strings are read-only slices of bytes](https://blog.golang.org/strings). They can be turned into Unicode code points using the `for` loop or by casting: `[]rune(str)`. However, multiple code points may be combined into one user-perceived character or what the Unicode specification calls "grapheme cluster". Here are some examples:
|
||||
|
||||
|String|Bytes (UTF-8)|Code points (runes)|Grapheme clusters|
|
||||
|-|-|-|-|
|
||||
|Käse|6 bytes: `4b 61 cc 88 73 65`|5 code points: `4b 61 308 73 65`|4 clusters: `[4b],[61 308],[73],[65]`|
|
||||
|🏳️🌈|14 bytes: `f0 9f 8f b3 ef b8 8f e2 80 8d f0 9f 8c 88`|4 code points: `1f3f3 fe0f 200d 1f308`|1 cluster: `[1f3f3 fe0f 200d 1f308]`|
|
||||
|🇩🇪|8 bytes: `f0 9f 87 a9 f0 9f 87 aa`|2 code points: `1f1e9 1f1ea`|1 cluster: `[1f1e9 1f1ea]`|
|
||||
|
||||
This package provides a tool to iterate over these grapheme clusters. This may be used to determine the number of user-perceived characters, to split strings in their intended places, or to extract individual characters which form a unit.
|
||||
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
go get github.com/rivo/uniseg
|
||||
```
|
||||
|
||||
## Basic Example
|
||||
|
||||
```go
|
||||
package uniseg
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
|
||||
"github.com/rivo/uniseg"
|
||||
)
|
||||
|
||||
func main() {
|
||||
gr := uniseg.NewGraphemes("👍🏼!")
|
||||
for gr.Next() {
|
||||
fmt.Printf("%x ", gr.Runes())
|
||||
}
|
||||
// Output: [1f44d 1f3fc] [21]
|
||||
}
|
||||
```
|
||||
