A simple way is to use. When specifying the sort key, drop all the diacritics. For example, "Bài viết" page would be.

You can also specify sortkeys for each category like this:.

I haven't tested if this would work in Wikia, but like I said it's what Wikipedia recommends. You seem to be using English Wikipedia as an example, which is a bit fallacious considering that we're talking about a fully Vietnamese wiki. Looking at a random category on Vietnamese Wikipedia, they seem to be doing it exactly as the OP is intending, and I doubt they're using shenanigans of Javascript or sortkeys to do it.

Itsuki Lee, I'm sorry if you haven't been getting the answers you were hoping for. I have no idea what I'm doing, because I have never worked with this variable, but this site and #mediawiki seem to indicate that setting $wgCategoryCollation to 'uca-vi' would fix your problems.

That, however, is something that Staff would have to do. Drop them a line at c:vi.avatar:Special:Contact/features and perhaps ask about implementing this on all Vietnamese wikis, 'cause it seems like a pretty obvious fix.
