> Dog in bold, italics, red, green, uppercase, lowercase, initialcaps, smallcaps, are all the same word. But that is a feature of the word Dog, try the German words maßen (limited amounts) and massen (large amounts), historically they share the same upper case rendering MASSEN. Now someone versed in German could change to the alternative MASZEN or use the rather modern upper case version of ß. However the default naive (and most of the time correct) conversion between cases looses a significant amount of information.
