Not really -- there's nothing "special" about the *symbols* at all.
Frank is right: the difficulty is in (re-)parsing them, which needs to
happen when loading a patch, which means "funny" characters like spaces
would need to be escaped when saving a patch, but pd lacks an escaping
mechanism (e.g. in binbuf_text(), binbuf_add(), etc.).

It's certainly not comfortable to create such symbols, but it is
possible: you can use [list2symbol] from zexy to create symbols with
spaces quite easily.  Even in vanilla pd, you can do:

[makefilename foo%cbar]

... which will create & print a single symbol "foo bar" (pipe it to
[list length] if you don't believe me ;-)
