Hi Cor-el, thanks for your reply. Font Book has not reported any issues with Asian fonts. Today I was able to change the JP font used by Firefox, which for some reason it didn't let me do yesterday. That fixed the issue for me, even though it still glitches out occasionally (like when I type something out, and it initially gives me the Chinese version before fixing it into the Japanese version a second later). Hope things will stay OK from here on out :-)
