Note that there is an issue with this approach, which is that
attribute runs that start in the middle of a grapheme cluster might
result in odd behaviour wrt normalisation. However, it generally
doesn't make sense to have such an attribute run (it's the
equivalent of asking for e.g. a bold "o" with an italic umlaut,
which makes no sense), it's just something that you might want to
be aware of.
Sometimes it's desirable to have such attribute runs. One example is
to highlight combining marks using a different foreground color than
that of the base character.
That's a good point, and if you needed to support that then you'd have
to be very careful dealing with this issue. I guess it's more common
to do that kind of thing for display only?
Kind regards,
Alastair.
