Method Summary

String	convert(byte[] b) Converts the given byte array to a string by filling up each consecutive 2-byte-tuple with 0's to the size of the Unicode characters.
byte[]	convert(String s) Converts the given string to a byte array by chopping away all but the two least significant byte of each character.
int	convertedLength(String s) Returns the number of bytes required to store the converted string.
int	getTag() Returns the ASN.1 tag of this type which is [UNIVERSAL 30].
