C# Unity function to escape URL querystring parameters
I'm looking for a C# or Unity function to escape a URL querystring parameter the same way that the javascript escape function does it.
I've tried the WWW.EscapeURL but it seems to produce multiple character encoding for a single character e.g.
WWW.EscapeURL("De Grâve"); // De+Gr%c3%a2ve
I'm looking for :
De%20Gr%E2ve
This seems to correspond to a javascript call using the escape function:
escape('De Grâve') // = De%20Gr%E2ve
encodeURI('De Grâve') // = De%20Gr%C3%A2ve
encodeURIComponent('De Grâve') // = De%20Gr%C3%A2ve

I ended up using the escape method pulled from the Microsoft.JScript.dll
[NotRecommended("escape"), JSFunction(JSFunctionAttributeEnum.None, JSBuiltin.Global_escape)]
public static string escape(object @string)
{
string str = Convert.ToString(@string);
string str2 = "0123456789ABCDEF";
int length = str.Length;
StringBuilder builder = new StringBuilder(length * 2);
int num3 = -1;
while (++num3 < length)
{
char ch = str[num3];
int num2 = ch;
if ((((0x41 > num2) || (num2 > 90)) &&
((0x61 > num2) || (num2 > 0x7a))) &&
((0x30 > num2) || (num2 > 0x39)))
{
switch (ch)
{
case '@':
case '*':
case '_':
case '+':
case '-':
case '.':
case '/':
goto Label_0125;
}
builder.Append('%');
if (num2 < 0x100)
{
builder.Append(str2[num2 / 0x10]);
ch = str2[num2 % 0x10];
}
else
{
builder.Append('u');
builder.Append(str2[(num2 >> 12) % 0x10]);
builder.Append(str2[(num2 >> 8) % 0x10]);
builder.Append(str2[(num2 >> 4) % 0x10]);
ch = str2[num2 % 0x10];
}
}
Label_0125:
builder.Append(ch);
}
return builder.ToString();
}

That's weird - because WWW.UnEscapeURL worked for me converting for instance "%20" to a space.
HttpUtility.UrlEncode should do the trick for you: http://msdn.microsoft.com/en-us/library/system.web.httputility.urlencode(v=vs.80).aspx
It's available in .NET 2.0, so should work in Unity.
Then I'd have to pull in the System.Web assembly (I couldn't import it with a vanilla C# Unity project).
