Save original title of wiki

Description

I have a repo in which some wiki articles are written in Vietnamese. Because of this, the title should be in Vietnamese. I tried create a new wiki, there is no title field, so I write to slug field this title "Kiến trúc phần mềm". After saving the article, the title becomes "Kien truc phan mem", the page slug is "kien-truc-phan-mem".

Proposal

Can we have a separate field for title, instead of converting it to slug and then incorrectly recover it from page slug?
