Well, it's a long time since I looked at those macros, but it appears  
that you can't use \char{...} within a \class definition. Actually,  
that wouldn't be the appropriate way to use \char anyway; it would be  
\char97 or \char"61 to print an 'a'. (No braces.) But I suspect the  
\class definition probably only accepts literal characters. (What  
error did you get with the \N{...} entries once you had added the  
missing brace? It wouldn't have been the same as what you've shown  
here.)
