Since i did the suggesting, I suppose it behoves me to reply :). But let
me say that I haven't looked very closely at what you require, it just
looked similar.

The javadoc is completely off! Also, I am not sure if the method that
takes only the byte array is correct... I think we mostly use the above
method.
> * Take a string, and return little endian unicode bytes
public static void putUnicodeLE(
final String input,
final byte[] output,
final int offset)
the output is not returned, but put into the byte array.

?? What's closest? taking only the low bytes? I dont think there's
anything that does that (there were, but they were bugfixed out :)

public static boolean isUnicodeString(final String value) does the
checking, and returns true of false.
public static void putCompressedUnicode(
final String input,
final byte[] output,
final int offset)
converts to a US-ASCII byte array, or throws an java.lang.InternalError

Thanks! the term Compressed/Uncompressed unicode is an unfortunate
Excel'ism that's got into our code.
Hope that helps. I'm pretty sure the above is correct, but...
Shout if you need anything else.
