I had earlier MM not updated for some time (running on jessie) - think 2.1.2 version as previous had some polish translation bugs and it was working fine, however my SD card died and had to redeploy from scratch.

Have read that the font folder / approach to fonts has been reworked and I have the bad feeling something didn’t go as planned but have noone to confirm if it is only my issue or “version-wide”

I’m running RPI3 too… I have fresh install and this worries me a bit what could go wrong or where to look for error.
Did git pull && npm install again, it didn’t help. Locale in system is set to en.gb.utf-8 but I suppose it shouldn’t matter.
In MM language is set to ‘pl’

It looks like this:

Hi,
I have installed MM and it works fine, however I have issue with some letters typical to polish language - ś, ż, ł, ę - on mirror font for this letters is different from the other letters and it doesn’t look good / neat overall. Any tips how to deal with that ?
