- * Make a value safe for injection as a URL.

- * This encodes unsafe characters with percent-encoding and skips already
- * encoded sequences (see `normalizeUri`).
- * Further unsafe characters are encoded as character references (see
- * `micromark-util-encode`).
- *
- * 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]` (this is what `github.com` allows).
- * If the URL includes an unknown protocol (one not matched by `protocol`, such
- * as a dangerous example, `javascript:`), the value is ignored.
- *
- * @param {string | null | undefined} url
- *   URI to sanitize.
- * @param {RegExp | null | undefined} [protocol]
- *   Allowed protocols.
- * @returns {string}
- *   Sanitized URI.
