Bad font detected error

When I go to "https://support.apple.com/ja-jp/ht201361", the error message
"Bad font detected"(translated from Japanese to English, because my machine is in Japanese) popped up.
All Japanese characters disappear, remaining some words in Latin alphabets.
(Refer to attached img 1)
Clicking "Inspect element" in context menu, and I searched about font, I've found sentence included Japanese font like this.
<link rel="stylesheet" href="//www.apple.com/wss/fonts?families=SF+Pro+JP,v1:200,300,400,500,600|SF+Pro,v1:200,300,400,500,600|SF+Pro+Icons,v1" type="text/css" media="all" />

Similar phenomenon occurs in Adobe site "https://helpx.adobe.com/jp/acrobat/kb/2463.html".
A uppercase letter "A" in a square appears everywhere. (Refer to attached img 2)
I've found this line in a site source.
<style>body{font-family:"adobe-clean-han-japanese",sans-serif;}</style>

Sorry for my poor English!

   Thank you for the detailed report. Certain webfonts are known to be incompatible with 10.4 and 10.5. Unfortunately, due to other limitations, it is not possible to detect them automatically. We maintain a blacklist of bad fonts, and the browser will select an alternative with the same character.

   Using the steps in this earlier support ticket, are you able to find the font URL that causes the problem for you? I can make a guess from the Apple URL, but not the Adobe one. If you can provide both, I will add them to the internal blacklist for the next release of TenFourFox.

   My 10.5 shows no message box but the text also disappears.
   Workaround: Press Esc in time.

   The Apple URLs will be blocked. Thank you for performing those steps.

   The Adobe one is a weird case. It's actually being loaded over JavaScript. I suspect the URLs are coming from Typekit, but I'll need to do some additional investigation. This problem is now being tracked as issue 513: https://github.com/classilla/tenfourfox/issues/513

   I have found another bad fonts error on google calendar.
   Same situation in previous case. Latin alphabets display correctly, only Japanese characters disappear.
   Would you mind considering putting these fonts in blacklist?
   The number of font URLs is large this time though, I write down below, just in case.

   Yes, those can be added. We have a way of blocking entire font family URLs by pattern.

   I understand those fonts can be handled systematically.
   Please add those fonts in blacklist. I hope it'll fix the problem!

    This issue has been fixed internally and will be available in the next beta, which should be out in a week or two.

    After downloading TFF FPR 9 beta 1, I confirmed that I was able to read three sites (Apple, Adobe, Google Calendar) without a problem.
    Thank you very much!
