aptsh has a color prompt, and uses readline. Readline requires that in the prompt, all non-printable characters (e.g. color changing escape sequences) are enclosed between \001 (^A) and \002 (^B).
I suspect it's a bug in aptsh that its prompt doesn't have a balanced pair of \001 and \002 bytes, hence readline prints some of the \001 characters in the terminal. ** Package changed: vte (Ubuntu) => aptsh (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to vte in Ubuntu. https://bugs.launchpad.net/bugs/1237594 Title: The U+0001 control character is output in terminal Status in aptsh package in Ubuntu: Confirmed Bug description: when using aptsh (which uses color for its prompt), the xfce-terminal displays odd looking boxes with 1's and 0's (U+0001 control character) no matter what font I choose (even default font). This happens with other terminals (lxterminal, gnome-terminal, etc.) and other applications as well. It does NOT happen when using xterm or pterm, directly.
