The real problem is that Yarn is a text-mode reader. Meaning that,
instead of drawing pretty graphic pictures (that look to us like
characters), Yarn is limited to the text-mode "glyphs" that the
underlying Operating System supports. IBM-DOS (and OS/2) *do*
provide CP850, which contains all the "glyphs" necessary to display
ISO-8859-1. For ISO-8859-2, CP1250 is available for Windows, and
I think CP852 for DOS. But today's Operating Systems weren't really
written for a world in which one incoming message uses 8859-1, and
the next message uses 8859-2. So while a version of Yarn COULD be
constructed to display "high-ASCII" characters as though they were
from ISO-8859-2, such a version probably would *NOT* display ISO-
8859-1 correctly. When Operating Systems display UNICODE in text
mode -- maybe then. (Anyone rewrite Yarn as a graphics application,
allowing it to draw whatever-looking output is appropriate?)
