[Flatpak] Lollypop not showing certain Japanese characters

[rdrms]

Hi all, been using the flatpak version of lollypop for a bit now and like it a lot! I'm having an issue where Japanese fonts appear as boxes, not all of them - artists appear correctly (one didn't, but that one had malformed tags), only things that don't appear correctly are song and album titles. I'm at a loss as to why this happens.

For instance, this file:

Filename: /home/ryan/Storage/Music/Runa Miyoshida/美吉田 月 - Ska Flavor #2 【320K】 (2009.9.16)/03 やさしさに包まれたなら.mp3
Format: MPEG-1 Layer 3 - ID3v2.3
Size: 10.2 MB (9.7 MiB)
Length: 4:14
Bitrate: 320.0 kbps
Sample rate: 44100 Hz
Channels: Stereo

The artist appears correctly, but the song titles are all boxes.

Is there a font I need to install or something? I have fonts-takao-mincho installed (was installed by default on my distribution) and japanese fonts work flawlessly in other applications such as the terminal based mpd client ncmpcpp. I have allowed lollypop full access to the host filesystem. I've attached a screenshot of the two programs both displaying the same album, as you can see the English characters appear correctly but in lollypop it's just boxes for the Japanese characters.

OS Information: elementary OS "Odin" Development Preview, based on Ubuntu 20.04.x
Lollypop version: 1.4.18

I'm not sure what and how. I've tried to reproduce the issue and I had this:

(Caveat Emptor, I have no idea what the characters mean)

Can you try install the following packages?

sudo apt install fonts-noto-cjk fonts-noto-cjk-extra

This should ensure that you have all the Ubuntu provided CJK fonts.

@Eonfge those two packages were installed by default by my distribution, and are now set to manually installed. It's really strange, because the PPA version of Lollypop displays song titles just fine, but the flatpak does not. Maybe it's not picking up on certain fonts in the system?

[Eonfge]

Mmh. I've looked into it a bit more, and I think it's Flatpak related issue. Can you look at this issue and tell my if your fonts are installed in the right location:

flatpak/flatpak#924

I know too little about localization, and since it works on my machine, I fear that it's something Flatpak related or Ubuntu 20.04.

Wait, which flatpak version do you have? Can you do the following for me:

$ flatpak --version

I've noticed this too. IIRC, it used to work fine and just broke recently. I suspect it was either caused by the move to gnome 40, or by a recent update of gnome 40.

FTR, I'm using Debian sid, flatpak 1.10.2.

I checked upstream and they have an issue about this dating back to Juli 2019...

Honestly, I think it's something about your setup since reproducing it has proven to be nigh-impossible. I'll give it another shot with Elementary OS 5.1, but it's a tough one to pin-point the responsibility.

[rdrms]

I was running a prerelease version of elementary so it could have been misconfigured. I no longer run elementary and can no longer reproduce it so I'll close the issue.

[rdrms]

Oh shoot. Didn't realize it affects someone else. I'll reopen it and see if we can help the friend with Debian.

[Eonfge]

I've given it another shot but with no success:

On the left you can see my test-files, with different codecs and metadata, and on the right Lollypop. Only the .WMA test file is not displayed since I didn't include the non-free codecs in this test. Japanese characters are rendered properly though.

I'm closing this until I have something to work with. If you can reproduce this issue
