Warn about backtick and other characters in unquoted attributes
Last modified: 2015-04-01 09:45:19 CEST
In IE, the backtick ` is parsed as a quote character for attributes. It would be good to warn when it's the first character of an unquoted attribute value.
WebKit requires quotes when using one of U+0000 to U+0020 inclusive, so it would be useful to warn about such characters in an unquoted attribute value (if any of them are allowed and aren't already defined as whitespace).
