That's a problem. The above example looks good in a Ubuntu terminal window and in Firefox, but misaligned in the "gedit" text editor. In the SciTE editor, the line drawing characters show as four hex values in a box. groff, even with the "preconv" preprocessor for Unicode, can't display them either.
The box drawing characters aren't even in the astral planes. They're in plane 0 in the 0x2xxx range. So even old 16-bit Unicode implementations should support them.
(The TCP header from an RFC was just an example. I'm converting some old troff documents to PDF, and they have lots of box drawings.)
