	charMap[ord(string.upper(fromValue))] = toValue
	charMap[ord(string.lower(fromValue))] = toValue

That's backwards:
	self.charMap = string.join(charMap, "")

	rePattern = string.join( map(re.escape,fromVals), '|' )

The '+' operator works fine on strings in Python 1:

  rePattern = r'\b(' + string.join(map(re.escape, fromVals),'|') + r')\b'
