Browsers should use the u flag when matching the input value against HTML pattern attribute. (Spec.)

Initial implementations didn’t use the flag, but now at least Chrome, Firefox and Safari Technology Review 53 do.

A test case:

<form>
   <input value="a𝌆b" pattern="a.b" required/>
   <button>Test</button>
</form>

Maybe an additional note for https://caniuse.com/#feat=input-pattern would suffice?

Any suggestion?
