I see. Thank you very much for the explanation!

Then it is probably a bug in the KDE konsole that it tries to find
fallback fonts for languages not supported by the font selected in the
setup by using some equivalent of "fc-match :lang=fa:spacing=100"
instead of "fc-match monospace:lang=fa:spacing=100".
