wrong encoding of the window title in X11

[vejkse]

Context : I’m using imv 4.1.0 with xmonad in ArchLinux. My default encoding is UTF-8.

If I open a file named pétale….jpg with imv, the file name as it appears in the window title is “pétaleâ\302\200¦.jpg”.

With feh, the name is shown correctly. If use xprop on the feh window, I get several properties containing the window title: WM_NAME(STRING) and WM_ICON_NAME(STRING), containing the wrongly encoded version, and _NET_WM_NAME(UTF8_STRING) and _NET_WM_ICON_NAME(UTF8_STRING), containing the correctly encoded version. imv only has the WM_NAME(STRING) property.

According to https://specifications.freedesktop.org/wm-spec/1.3/ar01s05.html the window manager should use _NET_WM_NAME in preference to WM_NAME, which explains why xmonad shows the correctly encoded title for feh. So it seems that the problem would be solved if imv set the _NET_WM_NAME to the title. (See also https://stackoverflow.com/a/7706816.) Added: this may be useful: https://stackoverflow.com/questions/23273292/how-to-change-net-wm-name-x-library (I’m not sure).

Partial workaround: if set in my config file title_text = "$(echo "$imv_current_file" | iconv -f UTF-8 -t WINDOWS-1252)", the window title becomes: “pétale\302\205.jpg”, the “\302\205” appearing as a box for a missing character.

Hi, thanks for the detailed bug report. This is a good catch. I'll try to get this fixed for the next release.
