[xwiki-users] 4-byte UTF and XWiki (MySQL utf8mb4 encoding)

I have an XWiki installation, and I noticed that emoji's were not getting saved correctly and were rendering as question marks in XWiki. This is caused by MySQL's default encoding which is "utf8" and not "utf8mb4" (4-byte UTF to store the full unicode character set) To fix this, I am in the process of converting all my MySQL database tables into utf8mb4 encoding, which is turning out to be quite a lot of manual work. When XWiki creates the database tables for MySQL, can it use utf8mb4 encoding by default? Is this something I could open a bug request for?
