Shortcode parser includes quotes in attribute value

[tomaugerdotcom@…]

This appears to be new since 3.0.3. Any shortcodes using the following format:
[shortcode attribute="value"]

when $value is extracted, it now includes the quotes. IE: $value == ""value""; (as opposed to $value == "value").

As a result, any plugins that switch or parse $value without first stripping the quotes will now fail. This could potentially affect a lot of implementations. I can't imagine this is desired functionality.

After further inspection the following shortcode:
[shortcode attribute="value"]

yields the following:
$attribute == ""value"";

Can be fixed by changing line 229 of shortcodes.php to this:

$text = preg_replace("/[\x{00a0}\x{200b}]+/u", " ", htmlspecialchars_decode($text));

Can't reproduce on current trunk. Could you try this on a default installation without any custom plugins or themes?

Sounds like maybe an unfiltered HTML issue?

Yes, that must be it. I apologize for not trying this on a vanilla install before submitting. I'm new.
