Hi all.
First time posting here. I recently downloaded the dmd compiler 
and started making a few exercises with the language. Nice 
language features but still somewhat confused with the library.

If I use byDchar() over a "string" is there a possibility to 
get part of a character or is guaranteed that the entire visual 
character will be in the dchar?

Also, is there a way to peek into a range? Maybe a range that 
buffers its items when calling peek()?

Thank you

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'
}
