This utf-8 coded document offers those characters which are not in the Latin-1 repertoire, both as &#number;
representations and as utf-8 coded characters. Disclaimer: I don't speak or read Welsh: this test page is only for the purpose of testing the character-display technology in web browsers.
A.Prilop also offers a test page for &#number;
representations and another page with the utf-8 coded characters, covering these characters and many more. The two forms should be identical as far as HTML is concerned, but some differences are still observed in currently-available browsers.
