This has already been discussed in earlier submissions
of the driver, the utf16 format is HP specific (prefixed
with a 16 bit le lenght, and the 0 length string needs
special encoding) so despite the name this is not generic.

It should probably be prefixed with hp_ because of this
though, to avoid potential symbol conflicts when builtin.

(and the same applies to other generic functions).
