Comment (by yawning):

 Replying to [comment:11 jason]:
 > Just tested it on zh-CN version of windows 8/10. On windows 10, it seems
 to me YaHei UI should also be whitelisted besides YaHei, otherwise it will
 break whole TB UI. But I could not reproduce it on windows 8.

 So MS changed the default UI font between Windows 8 and 10.  Beyond the
 extra fingerprinting risks having more fonts in the whitelist doesn't
 actually hurt, so adding the appropriate UI font seems like a reasonable
 way to fix this issue for now (With the whitelist getting bloated due to
 UI fonts being a bit of an orthogonal issue).

 I am ACKing arthuredelstein's branch.
