Some fonts not defaulting to system font

[Irihapeti]

OS version is Resurrection Remix (Android 10) on a Moto G7 Power
Collabora version is 4.2.11 from Google Play

I have an issue with font display. It seems that fonts which are not part of the system (or maybe provided with Collabora - I'm not sure) are displayed as Burnstown Dam, which makes them extremely difficult to read. However, if they are formatted as bold or italic, they are displayed as the system font, which is what I'd expect from the plain version as well.

I have the same version of Collabora on Android 9 (also Resurrection Remix) on a Moto G4 Play, and the problem doesn't appear. All versions of the fonts are visible as the system font.

These are all documents that originated elsewhere, either on my (Linux) desktop PC or received via email.

Screenshot is attached. Paragraphs 3 and 4, which are using system font throughout, are using Ubuntu font.

Update:

This seems to happen only on Resurrection Remix, which contains a number of fancy fonts.

A workaround, in case anyone else has this problem, involves editing /data/data/com.collabora.libreoffice/etc/fonts/fonts.conf, which requires root access.

Removing access to the /system/fonts folder gets rid of the fancy font, but renders most fonts as monospace.

Adding the following at the bottom of the file causes all undesignated fonts to default to the chosen font, Liberation Sans in this case.

<match target="pattern"> <test qual="all" name="family" compare="not_eq"><string>monospace</string></test> <edit name="family" mode="append_last"><string>Liberation Sans</string></edit> </match>

Using an alias such as sans-serif doesn't work; a specific font name is needed and it needs to be one found in /data/data/com.collabora.libreoffice/user/fonts

This is something of a corner case, and therefore I don't see much point in leaving it open.

Closed.
