[docs] [issue28393] Update encoding lookup docs wrt #27938

[Ville Skyttä]

Ville Skyttä added the comment:

I believe (but haven't checked) that additionally, encoding names are case insensitive with respect to the fast-path behavior. But then again I also suppose that's the way it was before #27938 as well, which is why I didn't change that in this patch. But why not add it while at it, if I'm correct. Something like this revised patch?
