 * Percent encoding replaces a character (like `\ud83c\udf69`) with its UTF-8 hex bytes (like
 * `%F0%9F%8D%A9`). This approach works for whitespace characters, control characters, non-ASCII
 * characters, and characters that already have another meaning in a particular context.

 *  Fix: Don't crash reading non-ASCII characters in HTTP/2 headers or in cached
    HTTP headers.
 *  Fix: Retain the response body when an attempt to open a web socket returns a
    non-101 response code.
