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
standardized variants for that particular
distinctions in the undotted part of that
family of symbols.
