I've got an odd problem/bug special char saved isn't

When I use fckeditor, I try and put in the curly braces in the editor and save it and it doesn't. example:

${SOME_VARIABLE}

(where I'm trying to literally put an example of code w/ ${VARIABLE} type format, its nothing magic I'm trying to do in fckeditor, I just want it to show the raw text)

when saved ends up as

$

not sure why? is {} a special set of characters in fckeditor? and if so, how can I output literal { and } instead of having them expanded or the like?

(FURTHER INFO) Sorry I found out it may be w/ the software we're using FCKEditor with... its knowledgebase software that does some kind of expansion on the { } but still the fckeditor isn't saving the data either, I tried using the FCKConfig.ProtectedSource.Add feature and the FCKConfig.ProtectedTags feature and neither works.

Thanks
