xterm binary package in Ubuntu Focal amd64

 xterm is a terminal emulator for the X Window System. It provides DEC VT102
 and Tektronix 4014 compatible terminals for programs that cannot use the
 window system directly. This version implements ISO/ANSI colors and most of
 the control sequences used by DEC VT220 terminals.
 .
 This package provides four commands: xterm, which is the traditional
 terminal emulator; uxterm, which is a wrapper around xterm that is
 intelligent about locale settings (especially those which use the UTF-8
 character encoding), but which requires the luit program from the x11-utils
 package; koi8rxterm, a wrapper similar to uxterm for locales that use the
 KOI8-R character set; and lxterm, a simple wrapper that chooses which of the
 previous commands to execute based on the user's locale settings.
 .
 A complete list of control sequences supported by the X terminal emulator
 is provided in /usr/share/doc/xterm.
 .
 The xterm program uses bitmap images provided by the xbitmaps package.
 .
 Those interested in using koi8rxterm will likely want to install the
 xfonts-cyrillic package as well.
