Method

voidcharToUnicode(char c)
char To Unicode 
System.out.println(Integer.toHexString(("" + c).codePointAt(0)));
StringcharToUnicodeEscape(char c)
Convert a character to its corresponding Unicode escape sequence. 
return charToUnicodeEscape(c, new StringBuilder());
StringcharToUnicodeLiteral(int value)
char To Unicode Literal 
String sTemp = Integer.toHexString(value);
sTemp = ("0000" + sTemp).substring(sTemp.length());
return "\\u" + sTemp;
voidcharToUnicodeSequence(final StringBuilder buf, final char ch)
char To Unicode Sequence 
buf.append("\\u");
buf.append(toHex((ch >> 12) & MAX_HEX_DIGIT));
buf.append(toHex((ch >> 8) & MAX_HEX_DIGIT));
buf.append(toHex((ch >> 4) & MAX_HEX_DIGIT));
buf.append(toHex(ch & MAX_HEX_DIGIT));
bytecharToUtf8(char ch, byte[] bytes, int start)
char To Utf 
int codePoint = (int) ch;
if (codePoint <= 0x007F) {
    bytes[start] = (byte) codePoint;
    return 1;
} else if (codePoint <= 0x07FF) {
    bytes[start++] = (byte) (3 << 6 | codePoint >>> 6);
    bytes[start] = (byte) (128 | (byte) (codePoint & 0x3F));
    return 2;

StringtoGreek(char c)
Return the unicode representation of a letter in the greek alphabet, where 'a' correspond to 'alpha', 'b' to 'beta' and so on 
StringBuilder txt = new StringBuilder();
if (Character.isLetter(c))
    txt.appendCodePoint(945 + c - 'a');
else
    txt.append(c);
return txt.toString();
