In my experience, Character Studio reflects what languages have been activated in the macOS system preferences for spelling. The settings below are in the macOS System Preferences > Keyboard pane, Text tab (yes, it's pretty hidden). Once you get to that Text tab, go to the Spelling: dropdown, and at the bottom of the dropdown will be Set Up…. That brings you to this screen:

With the settings I have above, Publisher only offers me the choice of "English" and "Français." If I check more options in that macOS spelling preference, Publisher updates accordingly.
 

I'm having serious issues with the Boolean operations in the Designer. Here is an example of a super easy mandala made out of circles. The effect is not only lagging but most importantly super unexpected and the software starts to be unreliable.
I tried with and without pixel snapping, with and without symbols, filled and not – no luck. What is more frustrating is that every time I get slightly different effect, none of which is the desired one.
The Boolean operation ar absolutely necessary for me. If you're not planning to fix them in the coming days/weeks, please let me know – I need this project to move forward and the Affinity tool is completely unreliable.

Hi Ivan Kr,
Welcome to Affinity Forums
Currently Affinity Designer doesn't have a vector (or raster) based perspective distortion tool. He hope to add it later in an future version.

I hope to because this is must have if you ask me!
