 *  Fix: Strictly verify hostnames used with OkHttp's `HostnameVerifier`. Programs that make direct
    manual calls to `HostnameVerifier` could be defeated if the hostnames they pass in are not
    strictly ASCII. This issue is tracked as [CVE-2021-0341].

 * Percent encoding replaces a character (like `\ud83c\udf69`) with its UTF-8 hex bytes (like

 * characters, and characters that already have another meaning in a particular context.

 * Percent encoding is used in every URL component except for the hostname. But the set of
