I would say that it is primarily about searching for *any of a
given set of characters*.  It has nothing to do, necessarily, with
the difficulty of typing certain characters, and it has nothing to
do, necessarily, with not knowing which characters you want to
search for.

It's simply about wanting to treat a given set of chars as
equivalent for search purposes.  How you input a search pattern
(typing, pasting) is only one consideration, for operation.

Typing is only one consideration when defining default behavior.
It is of course a reasonable thing to consider.
