defaults to Simplified Chinese character variants if the language has not
been specified by a page.
> Ah ok. Shouldn't we be shipping a separate Noto variant for each ov the
CJKV (+TC) locales that we have bundles for? By default, someone that's
using the ja_JP bundle is likely going to hit pages with no language
specifier that are in Japanese...
That would be ideal, but it's difficult to implement because we're trying
not to leak the user's locale. We would need to ensure that the CJKVsc and
CJKVjp have the same apparent name exposed to Firefox, and the bounding
rectangles for every character are the same for each variant. It might be

(`about:preferences#content`->`Advanced`), the drop-downs for Serif, Sans-
serif, and Monospace are empty. I have no idea how Firefox handles fonts
named in Japanese (eg: `ＭＳ 明朝` whitelisted as `MS Mincho`), but I
can't select the fonts even though they're present on the system. Even
the `about:tor` page looks kind of horrible.

that's the only Japanese font available. I will look into whether it would
be possible to whitelist more Windows fonts. Are there some you would

Oops, I got confused -- in Windows TBB 5.5.3a, there are actually four
fonts whitelisted specifically for Japanese: MS Mincho, MS PMincho, MS
Gothic, MS PGothic.
Here's a page to check that all four Japanese fonts are available to
I notice that both serif and sans-serif choose MS PGothic. This seems
wrong, but it's true for vanilla Firefox as well.
On Windows, do you see important situations where TBB 5.5.3a Japanese text
is worse than Firefox? Not that we shouldn't fix vanilla Firefox text
rendering problems, but I want to fix TBB-specific problems first.
For example, ja.wikipedia.org looks basically identical on my Windows
machines on Firefox and TBB.
> Likewise, if it's whitelisted, why can't I select it as my Serif font
(It should at least appear in the dropdown...)?
I don't know why the dropdown is failing.
> I assume if I hack up my profile to use: `ＭＳ 明朝` for my Serif and `
ＭＳ ゴシック` as my Sans-Serif font that things will actually look ok,
but I haven't tried yet (Double width `Ｍ`, `Ｓ`, single-width ` `).
That would be very helpful if you find preference settings that make it
look better for you.
> It's worth noting that despite the fonts having been shipped since
Windows 3.1, we should not be whitelisting either if "the font has glyphs
that changed between versions" is an issue.
We decided, at this stage, not to try to protect users from that issue.
