I would just write a wrapper around g_utf8_to_utf16() that would use it
in a cycle until the full length is reached and handle the nul characters.

The string is terminated by a nul character or explicit length,
whichever comes *first* – this is the standard behaviour of all libc and
glib string functions.  Passing len < 0 simply means that the second
condition never realises.
