Created attachment 133995 [details] the error Hi, I am using snap package in neon kde which is based on ubuntu 16.04. I can't open any file that has arabic characters. please see the screenshot attached.
Please report it to Ubuntu https://bugs.launchpad.net/ubuntu/+source/libreoffice I doubt it will be solved as Canonical got rid of their only LibreOffice developer. You might want to look into Flatpak and we are getting AppImage packages soon.
This issue is already reported downstream at https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1674113
