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 pairin2- 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
-
decodeUTF8
public static int decodeUTF8(byte[] in, int used) throws java.lang.IllegalArgumentExceptionDecode a UTF8 character- Parameters:
in- array of bytes representing a single UTF-8 encoded characterused- number of bytes in the array that are actually used- Returns:
- the Unicode codepoint of this character
- Throws:
java.lang.IllegalArgumentException- if the byte sequence is not a valid UTF-8 representation
