Do anyone know of a true complete list of all katakana characters, including such combinations as ティ, トゥ, フェ, ヴぁ, ワ゛,　ン゛?

Because I've never seen those included in lists and it's pretty stupid because you think you know all of them, then suddenly you stumble upon weird ones such as those.

And like, how are you supposed to know how to write a "ti" sound with テ and not ト for example?

I need a COMPLETE list.
