Do you mean wide characters? If so, the current G_asprintf()
implementation will support whatever vfprintf() supports. For all
C9X-compatible implementations (including GNU libc 2.x), that includes
%lc and %ls.

The %s specifier deals with byte strings; it doesn't care about
encodings. The %c specifier deals with individual bytes; it can't be
used to write a multi-byte character.

C9X also defines fwprintf(), swprintf() etc, which output wide strings
using a wide format string. As almost nothing in GRASS understands
wide strings, there wouldn't be much point in providing an interface
to those.
