Thanks for looking into this!

Because I assumed/hoped that reducing the input from 4 to 3 values
automatically results in 16-bit.  But given your comment it seems I was
wrong.

In the UCA documentation I found "Briefly stated, the Unicode Collation
Algorithm takes an input Unicode string and a Collation Element Table,
containing mapping data for characters. It produces a sort key, which is
an array of unsigned 16-bit integers."  So I guess in the end we also
want to have 16-bit and should change the code.

I might give it another try, but I just lack the basic knowledge here so
it's really just "Let's try to remove some lines/change some values and
check if it still works".  Therefore help or someone else doing it,
would be very welcome, sorry.

Or should we just go as it is? At least make_unicode didn't complain.
