The locale parameter indicates the locale to be used to convert to upper/lower case according to any locale-specific case mappings. If multiple locales are given in an array, the best available locale is used.
|
|||
|
|
|
|||
|

Setting `locale: false` ignores the platform locale and uses the [Unicode Default Case Conversion](https://unicode-org.github.io/icu/userguide/transforms/casemappings.html#simple-single-character-case-mapping) algorithm.

Default: The host environment’s current locale.

```
