--- Comment #7 from Xiaodong Qi i2000s@hotmail.com --- Indeed, I was using an old version of winetricks. Now I update winetricks and the cjkfonts can be installed, but the interface still has "squares" instead of Chinese characters shown up.
$ winetricks --version 20160627 - sha1sum: 49a061ce0ce08797e4e11b7ae28a19ec58d04080 $ wine --version wine-1.9.13
