A CharEscaper that uses an array to quickly look up replacement characters for a given char value. An additional safe range is provided that determines whether char values without specific replacements are to be considered safe and left unescaped or should be escaped in a general way.

A good example of usage of this class is for Java source code escaping where the replacement array contains information about special ASCII characters such as \\t and \\n while escapeUnsafe(char) is overridden to handle general escaping of the form \\uxxxx.

The size of the data structure used by ArrayBasedCharEscaper is proportional to the highest valued character that requires escaping. For example a replacement map containing the single character '\u1000' will require approximately 16K of memory. If you need to create multiple escaper instances that have the same character replacement mapping consider using ArrayBasedEscaperMap.
