[Tab] should escape meta characters before sending to jquery

[ellemenno]

When tabPath is sent to jQuery in tab.js#L382, it does not escape meta characters such as !"#$%&'()*+,./:;<=>?@[]`{|}~, which can result in uncaught errors.

e.g. kramdown creates footnote fragment links in the format #fn:4, which results in the following error from tab.js+jQuery:

Uncaught Error: Syntax error, unrecognized expression: unsupported pseudo: 4

According the the jQuery docs, meta characters should be escaped via double backslashes (\\): http://api.jquery.com/category/selectors/

@lubber-de —thanks, that was fast!

It looks like FUI also has a supported SASS distro? hmm.. i'll look at this project more closely.
