It doesn't look exactly like it here.  In fact, it looks quite
different.  Although it could be that on your system Emacs uses
different fonts than those on mine.

But if 2 characters from 2 different fonts look the same on your
system, I think you should customize the Info faces to countermand
that.  I don't see any other solution.

It might, if you turn on character-folding in Isearch.  Unfortunately,
that is off by default.

Emacs doesn't provide any fonts.  Your system does.  On my system,
these two characters look different, even with my old weary eyes.

We did.  It works for me.
