The Unicode Basic Latin (ASCII) code chart has the following entries for the parenthesis code points:
0028 ( LEFT PARENTHESIS
= opening parenthesis (1.0)
0029 ) RIGHT PARENTHESIS
= closing parenthesis (1.0)
• see discussion on semantics of paired
bracketing characters
As far as I can see, the document has no further information on which "discussion on semantics of paired bracketing characters" it is referring to. I'm guessing it is about "left"/"right" vs "opening"/"closing", but I would like to know more.
When I search the web for phrases like "semantics of paired bracketing characters" I only get the same document in various versions.
What discussion is it referring to and where can I read it?
