New description:

 Masayuki Nakano writes (about Windows fonts):

 > We decided that we should change our default Japanese fonts from legacy
 "MS PGothic" (sans-serif) and "MS PMincho" (serif) which have bitmap glyph
 to modern "Meiryo" or "Yu Gothic" (sans-serif) and "Yu Mincho" (serif).

 We should consider updating "font.system.whitelist" to reflect this,
 although it depends on what fonts are available by default on most Windows
 systems. We should also check if any other default fonts have been added
 that we should include in our whitelists.
