That is because clisp is case-insensitive, and treats all its symbols as
uppercase, *unless* they are specified to be treated as special
characters, as lowercases, spaces etc. This is done by placing a \ in
front of that character, or surrond a sequence of characters with | as
you have done.

You can recognize the case of characters with the predicates
upper-case-p and lower-case-p.
