Reply to message «Cursor/rendering position bug handling unicode devanagari characters», sent 10:52:42 03 July 2011, Sunday by Paul.W Harvey:
Confirmed, but what exactly happens depends on the terminal: I observe different bugs in yakuake (konsole) and urxvtc. Some problems happen in gvim, but they are not that large: only when I switch from last but one character before last «'» to previous one I get additional thick black line to the left of last character before «'», which disappears once I redraw or hide this text by placing another window (X window, not gvim one) on it and then unhide it. By the way, in console semicolon turns into colon because it is for some reason moved some pixels down: even when displayed using `xclip -o -sel clip'. Editing of this line in zsh happens almost normally compared to vim: in konsole moving the cursor causes characters to change their vertical position and, sometimes, their shape, in urxvtc there are no problems at all, but almost all characters from the last string appear as rectangles.
