Changed default GUI font might help fingerprinting JA Windows users

As yawning noted in legacy/trac#17550 (moved) the default GUI font changed across Windows versions:

Windows XP -> MS UI Gothic (Not sure if this needs to be localized, don't have a box with this)
Windows Vista/7 -> メイリオ
Windows 8/8.1 -> Meiryo UI
Windows 10 -> Yu Gothic UI

This might aid in fingerprinting JA users which are on Windows.
