REGARDING Terminal emulator, (c) 1997-2015, The Konsole Devein KONSOLE terminal , Using: KDE Frameworks 5.18.0, Qt 5.5.1 (built against 5.5.1), The xcb windowing system ISSUE When typing using Devanagari Font Space (a) When typing an all consonant things are fine (b) When a diacritic is typed the space taken for fonts is less than two characters as the diacritic is added to the existing alphabet like a ligature mark. (c) The fault is the distance between end current end of line and the visible caret mark is incorrect It is as much as if two English alphabets were typed. --------------------------------- The bug also shows with other scripts with ligature marks I tested with Bengali, Hindi, Sanskrit Keyboards and the error shows in all
You are using a somewhat old version. Do you have a simple way of testing the issue and screenshots?
I don't have latest version (still on 4.x) but none of consoles - either text mode or in X/Desktops support displaying Indian languages properly. This is case with all terminal emulators in Linux desktops. This require some change in semantics of terminal emulation and rendering to properly show complex text characters.
Affects the latest version of Konsole too (version 21.12.3). Please find some screenshots attached.
Created attachment 148063 [details] The cursor is offset too much from the end of the Bengali text
(In reply to Puspam Adak from comment #4) > Created attachment 148063 [details] > The cursor is offset too much from the end of the Bengali text Can you please include the exact character string that is displayed in the image, and which font you use? I see something similar when I use Hebrew characters with a font that has no such characters, and fontconfig uses characters from another font with a different width. I guess that the solution is to display the characters in their place, one a t a time, instead of using drawText to draw multiple characters at a time.

I can see that the Bengali characters are not placed on separate blocks even when they are not joined (for example Bengali digits).

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 430822, bug 442742, bug 441037, bug 430822, bug 440070, bug 450017, bug 445846, bug 453086, 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
Let us know if you still have this issue on recent version
(In reply to Kurt Hindenburg from comment #9) > Let us know if you still have this issue on recent version Let me know which specific version to test? Would it suffice to test on Kubuntu 23.10 ? it has Plasma 5.27 . My debian has older konsole 20.12.3.
