This tests uses devanagari characters as an accesskey that is a single printable character and can be generated with a single keystroke, but that in some cases represent more than one unicode code point.
The test should be run using an INSCRIPT or devanagari keyboard, which has the relevant keys available. 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, then accesskey works with a single printable character that is multiple unicode code point, the HTML 5.2 spec as of 5.2 doesn't match reality and we should make a change, as per issue 485.
The second test uses a key which may not be available when using the alt-key as a modifier, because that typically generates a variant character.
The third test uses a "dead" key - one which would normally modify another, rather than producing a complete character. This test is for curiosity, since I don't understand Hindi enough yet to know what to expect here.
The fourth test uses a character that is generally available as a single keypress whether or not the alt or ctrl modifier keys are pressed, but not when the shift key is pressed.
