How to send a form field value that begins with '@'?

Hi.
With...
curl --form name=value http://somewhere.org
there is a bit of special syntax that applies to the value part in that if I say
curl --form name=@filename http://somewhere.org
it does a multipart form post, and transfers the contents of filename.
OK then: how do I transfer a literal value that starts with '@'. Is there any
way of sending a literal 'name=@some-string'? As far as I can tell from reading
the curl man page, the 'value' part isn't supposed to be URL encoded, so '@' is
a perfectly valid character that you might want to send.
I suppose I'm really approaching this from a security point of view - you might
have a case where 'value' is captured from a user, and there needs to be a way
of ensuring that what they type gets sent verbatim without the possibility of
opening some file and sending its contents. The same '@' trick works in
curl_setopt() in PHP too, and the same vulnerability arises.
Thanks
