             Bug #: 54062
           Summary: journalctl --setup-keys prints unreadable QR code in
                    wide CJK mode
    Classification: Unclassified

        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
        AssignedTo: systemd-bugs at lists.freedesktop.org

Start a terminal in wide CJK mode (ie "VTE_CJK_WIDTH=wide LANG=zh_CN.UTF-8
vte2_90" or "VTE_CJK_WIDTH=wide LANG=zh_CN.UTF-8 gnome-terminal
--disable-factory"), then run journalctl --setup-keys. The printed QR code is
badly broken, because it's created using the block characters which get width
2, mixed with spaces that get width 1.
