Support single characters having a catcode of 13 (active) or 12 (other),
and expand a macro defined for the character only if it's active.
This enables defining `~` as a macro, but avoiding expansion in URLs.

Fix#1786 (incorrect size of "E" in `\TeX`) by fixing `\raisebox` to

the argument is just as if it were in `\textrm{...}`.
