Have you tried using a html entity such as the below instead of the question mark:
& #63;
remove the space between the & and #. The forum will not let me post the full code as it reinterprets it.
A full list of entity can be found on this page

If you are a Sydney based MODX developer would love to hear from you. Please contact me.
Yep, it's the '?' character that's breaking it. Presumably because it's part of the MODX tag syntax, but can't be sure.
But I'm not looking for a workaround, I want to verify it as a bug. Output filters generally work on content input by users, who can't be expected to always enter the correct html entity.
