input, and unicode output, which have been broken due
to the change of the size of Rune from two bytes to
four bytes.
(Unicode-le and unicode-be output have not been
affected, since they work different, and produce
correct output as long as sizeof(Rune) >= 2.)
In all of the affected functions an extra array of N
elements of type u16int is used to temporarily store
the 16-bit unicode data. As this increases stack
usage, perhaps a different, slightly more complicated
solution might be preferred, where only a single
`Rune buf[N]' is used for both temporary storage and
the result.
