[nc] Testing: Arrange corpus for monospace testing

[Paul Sladen]

Collate a good corpus of texts for on-screen Ubuntu Monospace testing; this should show:

  single and double width CJK usage
  text-based email
  shell
  ssh/command-line sessions

On-screen the font is more commonly used gray-on-black, instead of black-on-white, and a good proportion of the samples need to show this.

Easiest format is probably going to be HTML, possibly with some grotesque table hacks to show double-width CJK on a correct grid. In GNU Screen the "hardcopy" command does not cope with UTF-8, but the Writebuf command does work with a copy more steps required:

   1. Take a PNG screenshot (as a reference, and for colours)
   2. Under GNU Screen, do:
   2a. Ctrl-a [ (start to copy region)
   2b. Select whole of terminal top-left to bottom-right
   2c. Press enter (save region to buffer)
   2d. Ctrl-a > (Writebuf)
   2e. Attach /tmp/screen-exchange with a sensible name
