* A {@code UnicodeEscaper} that escapes some set of Java characters using the

* unescaped) can be specified on construction.
*
*
* For details on escaping URIs for use in web pages, see section 2.4 of RFC 3986.
*
*
* 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)}.
*
*
* When encoding a String, the following rules apply:
*
* - The alphanumeric characters "a" through "z", "A" through "Z" and "0"
* through "9" remain the same.
*
- Any additionally specified safe characters remain the same.
*
- If {@code plusForSpace} was specified, the space character " " is
* converted into a plus sign "+".
*
- 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.
*
*
*
* RFC 2396 specifies the set of unreserved characters as "-", "_", ".", "!",
* "~", "*", "'", "(" and ")". It goes on to state:
*
*
* 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.
*
*
* For performance reasons the only currently supported character encoding of
* this class is UTF-8.

/**
* An {@link Escaper} that converts literal text into a format safe for
* inclusion in a particular context (such as an XML document). Typically (but
* not always), the inverse process of "unescaping" the text is performed
* automatically by the relevant parser.
*
*
* For example, an XML escaper would convert the literal string
* {@code "Foo"} into {@code "Foo<Bar>"} to prevent {@code ""}
* from being confused with an XML tag. When the resulting XML document is
* parsed, the parser API will return this text as the original literal string
* {@code "Foo"}.
*
*
* Note: This class is similar to {@link CharEscaper} but with one very
* important difference. A CharEscaper can only process Java UTF16 characters in isolation
* and may not cope when it encounters surrogate pairs. This class facilitates
* the correct escaping of all Unicode characters.
*
*
* As there are important reasons, including potential security issues, to
* handle Unicode correctly if you are considering implementing a new escaper
* you should favor using UnicodeEscaper wherever possible.
*
*
* A {@code UnicodeEscaper} instance is required to be stateless, and safe when
* used concurrently by multiple threads.
*
*
* Several popular escapers are defined as constants in the class
* {@link CharEscapers}. To create your own escapers extend this class and
* implement the {@link #escape(int)} method.
