I uploaded the rxvt-cygwin terminfo file from Cygwin onto the Linux
system (into ~/.terminfo/r/rxvt-cygwin). Setting TERM=rxvt-cygwin now
allows the curses-based program to draw boxes correctly, but
apparently some substitution is going on because it's using plain old
hyphens and vertical bars for lines and plus signs for corners.
Terminfo doesn't seem to know anything about Unicode as far as I can
tell (or does it?). That leads to the question of how putting the
terminfo file on the Linux system caused the curses-based program to
output single ASCII characters where previously it was sending Unicode
sequences... something understood how to interpret the Unicode box-
drawing characters and replaced them with the nearest ASCII matches
"+", "|" and '-'.
However, this IS NOT happening with Unicode quote characters. Here's
a snippet from the man page for terminfo itself, as displayed:

Those "‘" sequences turn out to be \xE2\x80\x99, which is the UTF8
encoding of the Unicode character "Right Single Quotation Mark)
(U+2019).
Here's the full terminfo entry (decompiled with infocmp):

Any insight ijnto what's going on and how to make it work correctly
would be greatly appreciated.
