For my particular project (it binds with something like finite

return dchar and change index passed by reference.
Is it interesting for community that I code this feature in
general way targeting in phobos for future?
For UTF, there's already std.utf.strideBack which does most of
the work. I don't know why there is no std.utf.decodeBack -
should be very simple to wrap over strideBack.
However, for grapheme clusters, there isn't yet a counterpart for
std.uni.graphemeStride/decodeGrapheme, which notably affects
std.uni.byGrapheme, which is currently not a bidirectional range.
Any improvement would be much appreciated.
