Say I have a simple form like this:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<div id="search">
<form method="GET" action="/super-action">
<input type="text" name="q" />
</form>
</div>
</body>
</html>
with an input like: @tags "Cinéma Whatever"
a form GET request results in a url that looks like: /super-action?q=%40tags+"Cinéma+Whatever"
Now I want to reproduce that with javascript in location.hash, with a pound sign instead of a slash, like: /super-action#q=%40tags+"Cinéma+Whatever"
But with the available functions, I get there results:
@tags%20%22Cin%E9ma%20Whatever%22 @tags%20%22Cin%C3%A9ma%20Whatever%22 %40tags%20%22Cin%C3%A9ma%20Whatever%22 %40tags+%22Cin%C3%A9ma+Whatever%22
The question: How can I make an input value, like @tags "Cinéma Whatever", look like what a form GET request would do: %40tags+"Cinéma+Whatever" using javascript?

According to RFC 1738, /super-action?q=%40tags+"Cinéma+Whatever" is not valid inside an URL:
Thus, only alphanumerics, the special characters "$-_.+!*'(),", and reserved characters used for their reserved purposes may be used unencoded within a URL.
That means that you can't produce a valid URL with that substring in it. You must encode the special characters " and é, otherwise the resulting string is not a URL.
The reason why you think this is valid might be that your browser plays tricks on you: It could be displaying the URL in partially encoded form to make it easier to read in the address bar. Try using a protocol analyzer like Wireshark to inspect the actual URL path sent across the network.
UPDATE: I quickly confirmed this, the HTTP header sent in reaction to a form submit is the following:
GET /?q=%40tags+%22Cin%C3%A9ma+Whatever%22 HTTP/1.1
So it is first UTF-8 encoded and then URL encoded.
