FIrefox unicode fallback symbols

Hello to the Arch Community,

this is my first post on here. I've run into a problem and can't seem to find a solution so I'm making this thread in hope of getting a solution or a hint at least. In my Firefox browser, instead of some symbols (i.e. Japanese katakana among others) I get unicode fallback symbols (the boxes with four numbers/letters inside). I tried changing the fonts in Preferences>Content but none of them display properly. I'm using Terminus as a default system font and it has no problems with displaying said symbols. Thus, my problem is unique to Firefox itself. I've tried changing changing the text encoding but no other options work properly. Is there a way to add Terminus to Firefox or an alternative solution to this problem?

Thanks in advance.

Re: FIrefox unicode fallback symbols

I can confirm this. I see the same behaviour.

Aside from Firefox I also found out when I tried out the new Skype for Linux client for a bit that it is showing similar behaviour (classic Skype works fine).
However, instead of a square with the code inside it just shows a blank square.
For Firefox I also tried to change fonts to no avail. The new Skype for Linux client has no option available to do so afaik.

I have not been able to find another program on my system that is showing the same problem.

Re: FIrefox unicode fallback symbols

Are your sure you have the required fonts? I need adobe-source-han-sans-otc-fonts to display some Asian character (but as I don't understand any Asian language, I don't have paid much attention to it).

Can you give us a link to a webpage that has the problem? It is important, otherwise we cannot test it.

Re: FIrefox unicode fallback symbols

From what I see the wikipedia page on Katakana will do. https://en.wikipedia.org/wiki/Katakana; the katakana characters are missing for me in Firefox here.
I personally can't read it either but I though I'd check the behaviour the OP was having to see if it was just him or not. I have not yet tried to install the font you mentioned, I'll give that a try at a later time.

I also noticed that the Firefox window title will show Katakana fine but the window title bar is handled by Gnome rather than Firefox so that's probably why that works fine.

Re: FIrefox unicode fallback symbols

I have all the symbols expect two of the Kana supplement (U+1B001 and U+1B002). Here is the list of the fonts I have instralled:

adobe-source-han-sans-otc-fonts
cantarell-fonts
dina-font
gsfonts
otf-latinmodern-math
terminus-font
ttf-dejavu
ttf-freefont
ttf-liberation
ttf-ms-fonts
ttf-oxygen
xorg-fonts-75dpi
xorg-fonts-alias
xorg-fonts-cyrillic
xorg-fonts-encodings
xorg-fonts-misc
xorg-fonts-type1
xorg-font-util

Have you installed adobe-source-han-sans-otc-fonts?

I'm having the same problem, and this fixed it for me! Here is something others can copy and paste into the terminal more easily:

pacman -S adobe-source-han-sans-otc-fonts cantarell-fonts dina-font gsfonts otf-latinmodern-math terminus-font ttf-dejavu ttf-freefont ttf-liberation ttf-ms-fonts ttf-oxygen xorg-fonts-75dpi xorg-fonts-alias xorg-fonts-cyrillic xorg-fonts-encodings xorg-fonts-misc xorg-fonts-type1 xorg-font-util

Now, we just need to find a package that'll fill in those two Kana supplements.

It’s hard to name unifont readable, much less nice .

Have you tried WenQuanYi Micro Hei?

If you could identify the glyphs/code points you could request their addition to adobe source han sans https://github.com/adobe-fonts/source-h … issues/115
Edit:
rereading thread they have already been identified as U+1B001 and U+1B002
