there is another issue with these symbols -- they appear among the mathematical symbols but, in the reference given, they are used as delimiters

I know of no other application for these symbols other than as delimiters -- are they used as mathematical operators?

and how, in general, would one define the properties for characters which may sometimes be operators, and sometimes be delimiters?

 Unicode does not use
