IN the XMLWriter class try

String findFirstInString: ' "' inSet: XMLTranslationMap startingAt: 1.

This should return 2, because " is an entry in the XMLTranslationMap,  
however it return 0, because the code does not consider the last  
character in the string could be a character we are interested in.

I'll note ByteString has a primitive that implements this method and  
that primitive does the correct thing.

mmm perhaps a simpler  example.

this example

'hi-' asWideString  indexOfAnyOf: (CharacterSet newFrom: ' -0123456789 
{}')

that fails and returns zero.

the follow example works, because 'hi-' is a ByteString and the  
method call resolves to asking the  class of the object to invoke the  
findFirstInString:inSet:startingAt:  found in ByteString which is the  
primitive call.

'hi-'  indexOfAnyOf: (CharacterSet newFrom: ' -0123456789{}')
