So there was some kind of improvement with rendering asian languages?
I manage a website that has both English and Chinese versions, and I've always experienced a lengthy delay of 3 to 10 seconds when opening any file containing UTF-8 Chinese characters. The delay still exists in the latest beta. Is this because Sublime is pre-loading all of the glyphs from the font file? I say this because if I close the file, then reopen it in Sublime, there is then little to no delay. This pre-loading effect doesn't seem to lessen the delay when loading other files with Chinese characters though.
It's annoying, but not really a bug per se.
