# truncate-utf8-bytes [](http://travis-ci.org/parshap/truncate-utf8-bytes)
|
|
|
|
Truncate a string to the given length in bytes. Correctly handles
|
|
multi-byte characters and surrogate pairs.
|
|
|
|
A browser implementation that doesn't use `Buffer.byteLength` is
|
|
provided to minimize build size.
|
|
|
|
## Example
|
|
|
|
```js
|
|
var truncate = require("truncate-utf8-bytes")
|
|
var str = "a☃" // a = 1 byte, ☃ = 3 bytes
|
|
console.log(truncate(str, 2))
|
|
// -> "a"
|
|
```
|
|
|
|
## API
|
|
|
|
### `var truncate = require("truncate-utf8-bytes")`
|
|
|
|
*When using browserify or webpack*, this automatically resolves to an
|
|
implementation that does not use `Buffer.byteLength`.
|
|
|
|
### `truncate(string, length)`
|
|
|
|
Returns `string` truncated to at most `length` bytes in length.
