Was it? 

He said that the task is "to write a StringBuilder or FastCat". I don't know what a 
"FastCat" is, but a 'StringBuilder' needs encodings. So 'byte[]' is a case of being 
focused on implementation rather than goal, a flaw you yourself often notice in 
people's queries, Arne.

So I have to ask, if your goal is to build a 'String', why would you use 'byte' when 'char' 
is for that purpose?

I presume to conclude that Roedy screwed up on that one.
