AFAIK, no. You hit an Error, and those shouldn't occur unless you 
go out of your way for them.

I'll look into it.

What's there to say? They all take a range of characters, and 
return it as a range of the corresponding requested type.

In the case of "byDchar", it decodes the string (while returning 
a "BadChar") for invalid encodings.

The others first decode using "byDchar", and then re-encode the 
individual dchars into the corresponding requested char-type.
