Type: var 𐋀; where the character before the semi-colon is U+102C0 (CARIAN LETTER G). Equivalently, try: eval("var \u{102C0};"); // (note that the escape sequence is expanded when evaluating the string) I get the error: SyntaxError: Invalid character '\u55296' I expect: no error (because U+102C0 is a letter). Note that the following code works as expected (no error): var \u{102C0};

Seems very basic, but I can't remember this come up before. Very surprising.
