Years ago, most text editing applications had the option to set the default file encoding to US-ASCII. Now I can't find any recent editor on Linux that allows you to choose ASCII. If the purpose is to restrict the character set to 7-bit ASCII, then choosing a superset like UTF-8 or ISO-8859-1 is not sufficient.
I would like to be able to use modern GNOME and Qt based desktop utilities, but I need to be able to set them up with US-ASCII as the default file encoding. Is there any way to do this on Linux (Debian)?
