Deleting forwards by one _character_ certainly makes life less harsh.
It's pleasanter than the UAX#29 suggestion, "For example, on a given
system the backspace key might delete by code point, while the delete
key may delete an entire cluster".

Evidence? It's easiest for displaying the cursor. I've encountered the
problem that, while at least I can search for text smaller than a
cluster, there's no indication in the window of where in the window the
text is. SIL's Graphite supports the idea of a split cursor, which
shows the glyphs corresponding to the characters before and after the
cursor position.
