We will need the weak and neutral categories (or at least a single
category for both of them) if we ever want to become more accurate
about the need for placing LRM/RLM to fix the display.  That's because
the display becomes "messed-up" when a strong R character is followed
by weak (e.g. digits) or neutral (whitespace, punctuation) characters.

But it is okay to add that later, if you don't want to do that now.

Yep.

Thanks.
