digitalmars.D.learn - error "Not the start of the UTF-8 sequence"

Hello,

I get this error message:
	Not the start of the UTF-8 sequence
without any other comment module name or whatnot.

This happens when I just added toString to the following struct, and used it:

     struct Node {
         // Note: level is equal to the number of chars up to this node.
         // Note: a 'path' node without entry has key="".
         char ch;
         uint level;
         Key key;
         Value value;
         ...
         string toString() {
             if (this.key != "")
                 return format("<%s %s:%s>", this.ch, this.key, this.value);
             else
                 return format("<%s>", this.ch);
         }
     }

Hints? I'm blocked :-(

Sorry, no, nothing to do with the type. The error came from a special case 
where ch='\0'. Seems some routine in dmd does not like that; but no idea where 
the error comes from.
There are two points to solve, I guess:
* The error message should tell where it happens.
* '\0' is a valid code point, should pass through without error.

if it's '\0', the error message is clearly incorrect, report a bug.
