-/**
- * A {@code UnicodeEscaper} that escapes some set of Java characters using the
- * URI percent encoding scheme. The set of safe characters (those which remain
- * unescaped) can be specified on construction.
- *
- * <p>
- * For details on escaping URIs for use in web pages, see section 2.4 of <a
- * href="http://www.ietf.org/rfc/rfc3986.txt">RFC 3986</a>.
- *
- * <p>
- * In most cases this class should not need to be used directly. If you have no
- * special requirements for escaping your URIs, you should use either
- * {@link CharEscapers#uriEscaper()} or {@link CharEscapers#uriEscaper(boolean)}.
- *
- * <p>
- * When encoding a String, the following rules apply:
- * <ul>
- * <li>The alphanumeric characters "a" through "z", "A" through "Z" and "0"
- * through "9" remain the same.
- * <li>Any additionally specified safe characters remain the same.
- * <li>If {@code plusForSpace} was specified, the space character " " is
- * converted into a plus sign "+".
- * <li>All other characters are converted into one or more bytes using UTF-8
- * encoding and each byte is then represented by the 3-character string "%XY",
- * where "XY" is the two-digit, uppercase, hexadecimal representation of the
- * byte value.
- * </ul>
- *
- * <p>
- * RFC 2396 specifies the set of unreserved characters as "-", "_", ".", "!",
- * "~", "*", "'", "(" and ")". It goes on to state:
- *
- * <p>
- * <i>Unreserved characters can be escaped without changing the semantics of the
- * URI, but this should not be done unless the URI is being used in a context
- * that does not allow the unescaped character to appear.</i>
- *
- * <p>
- * For performance reasons the only currently supported character encoding of
- * this class is UTF-8.
- *
- * <p>
- * <b>Note</b>: This escaper produces uppercase hexidecimal sequences. From <a
- * href="http://www.ietf.org/rfc/rfc3986.txt">RFC 3986</a>:<br>
- * <i>"URI producers and normalizers should use uppercase hexadecimal digits for
- * all percent-encodings."</i>
