Add Unicode symbol characters to operator charset. Remove '@' from the operator character set, but add the math, symbol, punctuation, arrow, and line- and box-drawing characters. Also allow operators to contain (but not start with) combining characters--this should be safe, because identifiers can't start with combining characters either, and we don't allow them anywhere else.
