ADDITIONAL INFORMATION

OK, so I'm closing this bug since it doesn't appear to be KDE related.
In fact I can reproduce it in other DE's.

For the record if anyone encounter this bug in the future:
1) It seems to disappear in Manjaro VM by following instructions in https://wiki.archlinux.org/title/Locale
2) It seems to disappear in Manjaro host OS with one additional step:
    after installing "nerd-fonts-hack" package from the AUR, it resolves the issue with all fonts afterwards. ?!?
    I have no clue why this worked though.
3) I haven't managed to resolve it in KDE Neon VM :/

Maybe the issue has to do something with glibc update since time correlates. 
On the other hand, same on the internet states 'Other>Private user area' section has to be used with the same font (or a compatible font) author has used. The odd thing, it used to work with "Hack" font and after the 2) it does once again.
Oh well...
