Created attachment 130033 [details] konosle variable width font error SUMMARY Konsole on Kubuntu 20.04 ( Konsole-19.12.3, KDE FX 5.68.0, Qt 5.12.8) does not support variable width fonts (eg. indic language fonts) and renders it as monospace. This results in unreadable output. However, Konsole on Kubuntu 18.04 (konsole -17.12.13, KDE fx - 5.61.0, QT 5.12.3) is rendering correctly. STEPS TO REPRODUCE 1. Open Konsole on Kubuntu 20.04 2. In the Konsole Terminal run the following commands $ echo தமிழ் வணக்கம் $ printf "\u0ba4\u0bae\u0bbf\u0bb4\u0bcd\u0020\u0bb5\u0ba3\u0b95\u0bcd\u0b95\u0bae\u0bcd\n" Both should print "தமிழ் வணக்கம்". 3. The rendered font is not readable. 4. When the same is tried in Konsole on Kubuntu 18.04 it is perfectly rendered. OBSERVED RESULT test is garbled.

Seems correct in master.
This is not about monospaced fonts, but about Unicode shaping. Konsole rendered characters individually to fix issues with Emoji, so Qt could not combine them via its text shaping algorithms. This should be fixed with Konsole version 20.08 to be released in the coming weeks, see bug 401094.
