The 3270 character for a graphics horizontal line is displayed using 2 bytes, the
"Graphics Escape" (hex 08) followed by hex A2, and in the Windows-1252
character encoding, hex A2 is a cent sign.
The 3270 character for a graphics vertical line is a GE followed by hex 85, and
in the Windows-1252 character encoding, hex 85 is an ellipsis, three horizontal
dots.
So the OP's emulator is probably handling Graphics Escape differently on W10.
Great explanation!
Warning: Windows-related notes below. Beware :)
Like you say, two bytes are coming in, but there's only one spot on the
screen for a character, so the 08 has to be stored somewhere else. In
Vista that's a separate character set buffer. That 08 tells the program
to switch from the normal font to the supplied GE font when drawing
those special characters. Now if the GE font is not available on the
system, Windows will typically revert back to the existing font, and you
get the cent sign (or other non-GE character) in error.
So to solve the problem I'd look for a GE font file supplied with the
emulator, and drag it to the c:\windows\fonts folder to install it and
see if that helps.
Another bit of information for the original poster: Vista (and perhaps
some other emulators), doesn't actually install the font into
c:\windows\fonts. That's because that directory is often protected from
non-admin writes, and I want people to be able to install and use the
program without admin authority, or run from a USB drive. Instead, the
font library is dynamically loaded, kind of like LOAD EP= at run time
using the Windows function AddFontResource().
I've heard of cases where AddFontResource() is blocked as a security
exposure by some company policies, with the only solution to temporarily
switch to admin and copy the font to c:\windows\fonts. Just guessing
that could be the case here with Win 10 involved.
