Best for whom? In what circumstance?

I _think_ you mean, for elements or attributes whose names contain
diacritical marks.

And the right answer is that good practice, where such names are used,
is generally to encode them all the same way.

Note also that if you get into Greek, for example, a single base
character can have two or even three diacritical marks, and the order in
which these are supplied, although generally creating the same
appearance, is significant in XML.
