# from_charset
`from_charset` is used to transcode a string from a given charset to the
internal charset. This is the exact opposite of the [to_charset
modifier](language-modifier-to-charset.md).
## Parameters
| Parameter Position | Type | Required | Possible Values | Default | Description |
|--------------------|--------|----------|------------------------------------------------------------------------------------------------------------------------------|--------------|---------------------------------------------------------------|
| 1 | string | No | `ISO-8859-1`, `UTF-8`, and any character set supported by [`mb_convert_encoding()`](https://www.php.net/mb_convert_encoding) | `ISO-8859-1` | The charset encoding the value is supposed to be decoded from |
> **Note**
>
> Charset encoding should be handled by the application itself. This
> modifier should only be used in cases where the application cannot
> anticipate that a certain string is required in another encoding.
