This problem has been reported to me by a number of people.  Someone figured
out that it was a problem with SunOS 3.4;  unfortunately, I only have access
to 3.2, so I was unable to try things out.  Luckily, I just received this fix
from D. Brent Chapman (capmkt!brent) [thank you!].  It works for him under 3.4 
and causes me no problems under 3.2:

---------------------- Start of forwarded message ----------------------

In the current version of SunOS (3.4), SunView ignores the WIN_FONT
parameter in the window_create() function call if you are creating a
window of type TEXTSW, and always uses the user's default font.  This
has been demonstrated, and is documented in passing in the WIN_FONT 
entry on page 332 of the SunView Programmer's Guide (Revision A, 15 Oct 86).
What this means is that notes in the notesDsply window show up in the
default font, rather than in monthtool.font, and therefore don't have
their typeChar (the little 'D', 'T', or 'Y' in a box, or the filled-in
box) displayed properly (they all show up as "^?").  Because of the way 
monthtool is written, I assume that in some past release WIN_FONT 
was _not_ ignored.  

It turns out the workaround for the problem I described previously is 
relatively simple; you just set the environment variable "DEFAULT_FONT"
to the monthtool font before you make any SunView calls.  Appended is a 
set of context diffs between your original code and my modified code.

I am at a loss to explain this one.  Please repost if this occurs again.
