You should just be able to call the range's .front method, which 
will do the decoding. However, calling .front on just a normal 
string without using byDchar will also work, as front 
automatically decodes by default.

void main()
{
	string s = "中文汉字";
	writeln(s[0]);       //Prints '?'
	writeln(s.front);    //Prints '中'
}
