* Further unsafe characters are encoded as character references (see

* `micromark-util-encode`).
|

*
|
||
* Then, a regex of allowed protocols can be given, in which case the URL is

* sanitized.
|
||
* For example, `/^(https?|ircs?|mailto|xmpp)$/i` can be used for `a[href]`,
|
||
* or `/^https?$/i` for `img[src]`.
|
||
* If the URL includes an unknown protocol (one not matched by `protocol`, such
|
||
* as a dangerous example, `javascript:`), the value is ignored.
