[Bug] OpenLink() fails on Unicode characters

[m4rcel]

When opening a Link containing Unicode characters, OpenLink() fails to properly encode the characters. It seems that they are encoded in ISO-8859 instead of the required URL-encoding.

Example ManiaLink [You have to change the path to the script at two positions in the script]:

Code: Select all

<?php

$param = htmlspecialchars(isset($_GET['param'])? $_GET['param'] : '', ENT_QUOTES, 'UTF-8');
header('Content-Type: text/xml;charset=utf-8');
echo <<<EOT
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<manialink version="1" background="0">
	<entry id="entry" name="inputParam" sizen="100 5" />
	<label id="label" posn="0 -10" style="CardButtonMediumWide" text="Send! (using ManiaScript)" ScriptEvents="1" />
	<label posn="0 -20" style="CardButtonMediumWide" text="Send! (using classic method)" manialink="http://localhost/test.php?param=inputParam" />
	<label posn="0 -30" textcolor="000F">{$param}</label>
	<script><!--
while(True) {
	foreach(Event in PendingEvents) {
		if (Event.Type == CGameManialinkScriptEvent::Type::MouseClick && Event.ControlId == "label") {
			declare Text Link = "http://localhost/test.php?param=";
			Link ^= (Page.GetFirstChild("entry") as CGameManialinkEntry).Value;
			log("OpenLink: " ^ Link);
			OpenLink(Link, ::LinkType::ManialinkBrowser);
		}
	}
	yield;
}
--></script>
</manialink>

?>

Enter something in the Entry field, using any special characters outside the ASCII code like accents, umlauts or whatever.
If you click on "Send! (using ManiaScript)", the called URL is with wrong encoding. Instead of having it urlencoded, it appears in ISO-8859-whatever.
If you click on "Send! (using classic method)", the link is called correctly, so its not a Server fault.
