I installed some other packages on Ubuntu 22.04.05 LTS, and while FLUKA still works, the fonts are no longer the same. At each entry I get “\u25be”, the program works fine, but the “\u25be” is quite irritating to see at every entry … Is there any way to reset the fonts and the way they are displayed in FLAIR? I have tried sudo apt-get update/upgrade but they haven’t been of much help.
For reference I am using Flair 3.3-1 with FLUKA 4-4.1.
either you are missing some system fonts that contain the unicode characters
you have selected different fonts in the setup that do not have unicode characters
you have a mix-up of python versions, e.g. you are running through anaconda
To eliminate/test:
You can try to select different fonts from the flair configuration dialog (Flair → Config → Fonts). By default flair doesn’t ask for any specific font but uses the system sans serif fonts, asking for different font-size only
you can run flair with a temporary ini file and check if everything is ok from the command line type: flair -i test.ini
If you are using anaconda try to run flair without the anaconda environment using the standard python/packages from the system
There are no options to change fonts really? Is there a way to reset them to the default on (e.g. a command)? Below in the image is what I have for fonts:
