Re: opening post
This requires a custom parser when pulling template parts in order to solve properly. Using regular expressions ignores noparse items, and using noparse functions garbles the output as above. Instead, a custom parser needs to be made to use noparse outside meta items, but still show it for meta text, and to encode only the items that are not wrapped in meta tags.
This is solved, but the fix has been applied only to 4.0.0 Alpha 1, since VaultWiki 3 doesn't support extending the parser in any of the ways I have mentioned.
