If so, you'll need to insert some []s to indicate that A-Z is one of a range of characters
I personally believe that (s)he has inserted those []'s, except that not having put code inside <code> tags as (s)he should have they rendered like hyperlinks due to the shortcuts available as part of the markup here at the monastery, à la A-Z. (ATM, that is: at a later time, someone reading this thread may hopefully find the root node duly edited...) To see the code closer to the way the OP really meant it you could try the xml view of the node.
