AIR SDK 17 - mailto subject line error for non English devices

Hi,

Is there a problem with language localization in AIR SDK 17 for iOS?

The following code works for an iOS 8 device with the language set to English but if you set it to any other language the subject line is missing!

var mailme:URLRequest = new URLRequest("mailto:hello@example.com?subject=CONTACT");
navigateToURL(mailme, "_self");    

Is there a fix for this?
