That, and line-drawing characters. Does anything but xterm support them?

"Line-drawing characters" are an object of your font and character set, not your terminal. In particular, they're used commonly in the IBM PC extensions to ASCII. Most terminals these days default to an ISO 8859-1 font, which is actually useful, or a Unicode font, in which case the application needs to understand to output Unicode.

Not completely, at least the way I (through the man page) understand it. xterm will draw them itself if your font doesn't have them.

Not just that. A genuine DEC VTxxx terminal and a good emulators of it (like xterm) has also a line drawing character set, enabled by a certain escape sequence, and there are lots of "legacy applications" that use it.

By the way, xterm still beats every other X11 terminal emulator I have tried in terms of stability and quality of emulation. Even the resource use is less than in most newer competitors, except rxvt. Since a terminal emulator is something that just needs to work reliably, no eye candy needed, xterm is the best. I don't see any point in reinventing this particular wheel.

Unfortunately its widget set was designed by the criminally insane.

That's a different set of line drawing characters. DEC terminals have
a line-drawing mode which is not at all related to IBM or ASCII. Good
terminal emulators support this because lots of curses applications use
it to draw text-windows and similar things.

Konsole and gnome-terminal both do.

You'll have to either play with your character set controls, or switch to UTF-8. Frankly, these days the latter action is actually simpler and works better: you can copy+paste a block of line drawing characters without having them end up as gibberish if both sides are UTF-8 aware.
