(tested in Korean and Japanese, on locale ko_KR.UTF-8) Reproducible: Always Steps to Reproduce: 1. Input CJK characters. Actual Results: characters are cutted in half. Expected Results: full character should be rendered. using kde lts 16.04.1
Created attachment 101292 [details] captured with ascii and CJK characters.
[Update] maybe this is because of the fallback font (right expression?) i changed the font to D2Coding, the free fixed-width font that includes korean glyph, and this problem solved. so i think, if setted font has no corresponding glyph, konsole find it on fallback font, and using two font occurs this error.
Created attachment 101293 [details] Japanese text is cut off I have the same problem. It's not restricted to Konsole since it happens in Kate/Kwrite as well. See the screenshot. I'm on KDE Neon. KDE Plasma Version: 5.7.5 KDE Frameworks Version: 5.26.0 Qt Version: 5.7.0
I don't know enough to pinpoint the problem, but I can say that various fonts exhibit the issue to varying degrees (some appear to have more "room" separating each line). I have changed the Kate font to "Noto Sans Mono CJK JP" which solves the problem for my own use case within Kate. The font isn't available through the KDE fonts menu for the "Fixed width" selection so Konsole still looks wrong for me.
How do non-Qt applications handle font fallback? If we used the height of the tallest character from all fallback fonts, there would be lots of spacing between the lines.
I suggest using Nanum Gothic Coding for Korean.
