Hei,

currently I've the following [pseudo] code:

	c = "";
	a = snprintf(buffer, 32, "%0d", day);
	b = snprintf(buffer, 32, "%s", daynames[dayofweek]);

	smartstr_appends(&c, a);
	smartstr_appends(&c, b);

	return c.c;

This snippet of code returns a legacy string. Now, as ICU provides the 
daynames as UTF16 encoded strings, I'm a bit lost as how to solve this. 
Of course I need to return a UNICODE string now, but which snprintf() 
like function should I use, so that %0d and friends are printed into the 
string as UTF16 string which I then can concat together, and return from 
the function?

Derick
