Method Detail

### getInstance

    public static UnicodeCharacterSet getInstance()

### inCharset

    public boolean inCharset(int c)

  Description copied from interface: `CharacterSet`
  Determine if a character is present in the character set

  Specified by:
    `inCharset` in interface `CharacterSet`

### getUTF8Encoding

    public static int getUTF8Encoding(char in,
                                      char in2,
                                      byte[] out)

  Static method to generate the UTF-8 representation of a Unicode character

  Parameters:
    `in` - the Unicode character, or the high half of a surrogate pair
    `in2` - the low half of a surrogate pair (ignored unless the first argument is in the range for a surrogate pair)
    `out` - an array of at least 4 bytes to hold the UTF-8 representation.
  Returns:
    the number of bytes in the UTF-8 representation
