Fast unicode input in Emacs with US layout
<p>I would like to have a quick way to input unicode characters with multicharacter sequences. For example to input <code>ä</code> I would type <code>\a</code>. Searching for this, I found <a href="http://wiki.portal.chalmers.se/agda/pmwiki.php?n=Docs.UnicodeInput" rel="nofollow">agda-input</a>.</p>

<p>While I could adapt the <code>agda-input</code> for my use, I don't really need the whole emacs mode for my purpose. So I was wondering if such thing already exists. </p>

<p>It is probably also not that difficult to code such input mode. I would appriciate if someone suggested on how to do that.</p>
