When inserting the three characters "\1%&" into a buffer the last two
characters are reordered as if they were L2R characters.  This only
happens on powerpc and aarch64, which is a strong indication that the
bidi code fails to take the signedness of char into account.  In fact,
compiling bidi.c with -funsigned-char is enough to break it.

Andreas.
