these seem to be of limited use since they treat utf-8 as a special case.

Are you the author of the library? Or how did you make a mistake? Did you change the library?

Well, it seems easier to maintain just one library instead of two, so if the bigger library contains
the functionality of the smaller one, I see no point in adding the small one...
