Thanks for your feedback!

I see, thanks.

Basically, lack of examples (that now you kindly provided) and,
perhaps, a little too terse info in the C standard and in the
glibc docs (that just talk about char*)

Also, seemed really weird that the very same info is used both for
char and wchar_t, in particular, that, for char, symbol_length == 2
actually means two _bytes_ not two chars (in your example)! Isn't
this a little counterintuitive?

Paolo.
