combining unicode points as accesskey test

This tests using something like accesskey="ñ" as a way to specify the "ñ" key, when available, as an accesskey

The test is easily run using a "standard" spanish keyboard, which has all the relevant keys available as a bare key. If you cannot activate or focus any links, then (probably) the accesskey attribute is ineffective and the results are not helpful. If you can activate the first and third but not second, then (probably) non-ascii keys work fine, but only if they are expressed as a single code point. If you can activate all three links, then the HTML 5.2 spec as of 5.2 doesn't match reality and we should make a change, as per issue 485.
