Interesting. This person has used
−−instead of--to introduce a comment, and got a syntax error as a result. Perhaps we can do something, either by sanitizing non-ASCII characters that are very similar to ASCII in copy and paste, or at least an explanatory error message, to indicate what the problem is.[-]User-reported unhelpful error message[/-][+]User accidentally uses a unicode long dash instead of ASCII dash to type a comment[/+]
