Created attachment 134331 [details] Demonstration of the problem in rendering I am using vanilla Konsole version 20.08.2 which came packaged with Kubuntu 20.10 I have tried many fonts, none has fixed this problem. The Unicode glyphs such as ➜ and ⚠ are not being rendered properly. Sometimes, the glyphs also push the glyphs to their right one space so that it gets rendered correctly, but this makes it very hard to edit such text. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Maybe a duplicate of Bug 422776? I’m not sure about the spacing issue though > Sometimes, the glyphs also push the glyphs to their right one space so that it gets rendered correctly, but this makes it very hard to edit such text. Could you explain this in more detail, and provide an example?
Created attachment 134557 [details] Example showing the weird behaviour when having double spaced unicode characters
Kindly see the new attachment for a visual demonstration. As you can see in the first prompt, the arrow "➜" pushes the closing double-quote into the "void", so that only half of it is only visible. However, when we place the cursor over that particular double-quote, it becomes fully visible, cropping the arrow to half the length. This makes editing such text in terminal very hard.
> Maybe a duplicate of Bug 422776? I’m not sure about the spacing issue though I have that bug as well but this one too. Maybe they are related, cause when I tried out the example shown in the other bug report, I could see the same problem there too.

Git commit 76f879cd70fb494ab2334d2660b34679546f3d9d by Kurt Hindenburg, on behalf of Matan Ziv-Av. Committed on 26/08/2022 at 19:24. Pushed by hindenburg into branch 'master'. Draw characters in exact positions QT can't be made to draw monospaced text (if the font does not cooperate), so avoid combining characters, using a QPainter::drawText() call for each character. For bidi text support this change requires konsole to reorder and reshape the characters. This is done using the ICU library (which QT also uses). This change allows for some improvements related to text rendering: - More precise bidi reordering, which is no longer changed by characters' attributes and selection. - underlines drawn separately from the text, allowing for differing underline modes (double, curly, dashed, dotted, colored). - Overriding font for emoji characters. This commit fixes a few bugs and addresses a lot more: Feature requests: More standard conforming RTL and various underlines: Related: bug 403729, bug 387811, bug 416508, bug 452087, bug 425973, bug 442742, bug 441037, bug 440070, bug 450017, bug 445846, bug 453086, bug 381593, bug 451716 Using non-monospace font: Emoji: Regression: devanagari rendering M +2 -0 CMakeLists.txt M +1 -0 src/CMakeLists.txt M +47 -25 src/FontDialog.cpp M +2 -1 src/FontDialog.h M +127 -23 src/Screen.cpp M +18 -5 src/Screen.h M +28 -13 src/Vt102Emulation.cpp M +0 -29 src/autotests/CharacterTest.cpp M +0 -1 src/autotests/CharacterTest.h M +1 -1 src/autotests/TerminalCharacterDecoderTest.cpp M +119 -29 src/characters/Character.h M +1 -1 src/characters/Hangul.cpp M +5 -4 src/decoders/HTMLDecoder.cpp M +1 -1 src/decoders/PlainTextDecoder.cpp M +3 -0 src/profile/Profile.cpp M +29 -0 src/profile/Profile.h M +101 -6 src/terminalDisplay/TerminalDisplay.cpp M +7 -0 src/terminalDisplay/TerminalDisplay.h M +42 -0 src/terminalDisplay/TerminalFonts.cpp M +12 -0 src/terminalDisplay/TerminalFonts.h M +542 -269 src/terminalDisplay/TerminalPainter.cpp M +40 -13 src/terminalDisplay/TerminalPainter.h M +2 -0 src/widgets/EditProfileAdvancedPage.ui M +113 -3 src/widgets/EditProfileAppearancePage.ui M +61 -3 src/widgets/EditProfileDialog.cpp M +6 -1 src/widgets/EditProfileDialog.h https://invent.kde.org/utilities/konsole/commit/76f879cd70fb494ab2334d2660b34679546f3d9d
