A double quote within a string literal is encoded using \e" and a backslash is encoded as \e\e. Backslash escapes like \en and \et -are recognized, as are hexadecimal escapes like \exFF and octal -escapes like \e123. +are recognized, as are hexadecimal escapes like \exFF or \exxabc and octal +escapes like \e123. Ambiguity between a hex escape and subsequent +text can be resolved by using trailing semicolon delimiter: "\exabc;d" is a +string consisting of the character U+0ABC followed by "d". The semicolon +delimiter disappears. To write a literal semicolon immediately after a hex +escape, write two semicolons, the first of which will be interpreted as a +delimiter. Thus, "\ex21;;" represents "!;". .SS String Quasiliterals |
