Package: fvwm Version: 1:2.7.0-3 Severity: minor Fvwm should filter out the non-printable characters for the window title.
The issue can be reproduced with xmessage -geometry 400x100 -title "$(printf "\u200E ABC")" Test (or with gxmessage). Due to the U+200E LEFT-TO-RIGHT MARK character, I get some strange glyph before "ABC". Without the space before "ABC", this glyph appears partly over the "A". Note: I first saw this issue with https://community-imdb.sprinklr.com/conversations/data-issues-policy-discussions/announcement-contribution-form-update/681b76ab20d5b71fad32eac8 whose title starts with the U+200E LEFT-TO-RIGHT MARK character, and I was wondering about the cause of the display issue. -- System Information: Debian Release: trixie/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable-debug'), (500, 'proposed-updates-debug'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 6.12.25-amd64 (SMP w/16 CPU threads; PREEMPT) Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages fvwm depends on: ii libc6 2.41-7 ii libcairo2 1.18.4-1+b1 ii libfontconfig1 2.15.0-2.3 ii libfribidi0 1.0.16-1 ii libglib2.0-0t64 2.84.1-2 ii libice6 2:1.1.1-1 ii libperl4-corelibs-perl 0.005-1 ii libpng16-16t64 1.6.48-1 ii libreadline8t64 8.2-6 ii librplay3 3.3.2-20 ii librsvg2-2 2.60.0+dfsg-1 ii libsm6 2:1.2.6-1 ii libstroke0 0.5.1-10+b1 ii libx11-6 2:1.8.12-1 ii libxcursor1 1:1.2.3-1 ii libxext6 2:1.3.4-1+b3 ii libxft2 2.3.6-1+b4 ii libxinerama1 2:1.1.4-3+b4 ii libxpm4 1:3.5.17-1+b3 ii libxrender1 1:0.9.12-1 ii perl 5.40.1-3 Versions of packages fvwm recommends: ii gnome-menus 3.36.0-3 ii python3 3.13.3-1 ii python3-xdg 0.28-2 Versions of packages fvwm suggests: ii cpp 4:14.2.0-1 ii libx11-protocol-perl 0.56-9 ii m4 1.4.19-8 ii perl-tk 1:804.036+dfsg1-5 pn stalonetray <none> -- no debconf information -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Pascaline project (LIP, ENS-Lyon)
