symbols in design table

I am new to SW and if my question has been listed before, then sorry, but I could not find any articles would be an answer to my question.

I'd like to know what symbols are allowed to use in Design Tables. I'd like to use "/" symbol in \$PRP@Description in a design table for Elbow.

Will using "/" in the content of the parameter be a problem? Are there lists of symbols I should not use in any files in Solidworks?

Thanks
