                    considered an error

According to grammar, LS and PS (0x2028 and 0x2029) are EndOfLine. But, if encountered while parsing an identifier, they're rejected as 'not allowed in identifier':

// ASCII end of line parses fine
int ascii
;
int ls
; // char 0x2028 not allowed in identifier
int ps
; // char 0x2029 not allowed in identifier
