Parenthesis in rss urls being escaped

A rather niche issue that is affecting me. I've created an API that converts the output from https://boardgamegeek.com/xmlapi2/hot?boardgame into an RSS feed that can be read using the RSS widget. However, if you look in the link the urls have parenthesis in them which get escaped. When I look at my glance homepage the image urls have %28%29 in place of ().

Is this something I can fix with a setting?

I'm fairly sure it's not an issue on my end as all my debugging indicates the () are being sent correctly and the escaping to %28%29 is happening on the glance server.
