## `maxBuffer` and Unicode

It is important to keep in mind that the `maxBuffer` option specifies the
largest number of *octets* allowed on `stdout` or `stderr`. If this value is
exceeded, then the child process is terminated. This particularly impacts
output that includes multibyte character encodings such as UTF-8 or UTF-16.
For instance, the following will output 13 UTF-8 encoded octets to `stdout`
although there are only 4 characters:

```js
console.log('中文测试');
```
