The HTML spec allows characters in ids that the CSS selector spec (used by jQuery) requires to be escaped. Is there some solution that has been overlooked by jQuery and the W3C?
http://www.w3.org/TR/2009/CR-CSS2-20090423/syndata.html#characters In CSS, identifiers (including element names, classes, and IDs in selectors) can contain only the characters [a-zA-Z0-9] and ISO 10646 characters U+00A1 and higher, plus the hyphen (-) and the underscore (_); they cannot start with a digit, or a hyphen followed by a digit. Identifiers can also contain escaped characters and any ISO 10646 character as a numeric code (see next item). For instance, the identifier "B&W?" may be written as "B\&W\?" or "B\26 W\3F".
