When will IMDB support full Unicode?

Since 2014, the messageboards have supported the full Unicode set, so it obviously isn't that hard. Why doesn't the main site support Unicode? Right now it's still mired in a Western European-centric interface, where all names have to be transliterated to be posted, despite the transliterations being debatable and unofficial. The submission form even recognizes individual Unicode symbols, but specifically disallows them!
