Hi,
Having a valid URL in the email containing encoding of special characters in the parameter of the URL e.g. %2F, will result in below Click-time URL.

Click-time maintains the encoding correctly up to this stage.
However, after calling this URL, the Symantic redirect reverts the encoding of the entire Click-time u parameter including the parameter q in the origingal URL. This results in an invalid URL containing e.g. / in the parameter.
/TRACK/external/download?q=163334d25b97aa7596a919cac654db2171f7f7c32uaWAjdhh11toDgMfv3R6dxNIxHlCu/B8mOMm6ZhNtXs18tC6kIjZXxlVgRhpt0+xGFNoaPmqBKMIJqjf8gTCjgiXqkinnC+w+66NLt8tFVwT5NIC/im0mBgqeSeeIKWjVlEAcnXxsUEUZqBHg8toDIGL6eR3CF0B9MWLgFvx4W9Tp1JXdbgP1J4pRwwoDYyQL7ou46sLfL/F9u3j4O/K98sggPpUX09wlq2neUqchFGbYtxq3Jp6JpYFV+5RiiwEew5oSt5Bb7DFaT8NpgPP7LnP6nAV4c7kPGemo8+5ojCRsjwbVcrfKJQA1RvOaf
From my view, this should be technically avoidable from Symantec side by maintaining the encoding of the original URL parameter.
As currently all URLs are breaking, fast help would be very much appreciated.
Many thanks,
Matt
