Thanks, list, especially Bill and Tom. Your timely explanations about how the GE works confirmed my suspicions about it being a missing font. My coworker with W10 was back in the office today, and we were able to do compares between W7 and W10. Turns out the people who did the build of W10 neglected to install the font libraries included with the emulator. My coworker copied the fonts from the emulator directory to the W10 font directory and all started working again. We will pass the information to our PC build folks and have them correct their build procedure.
To those who recommended switching to a different 3270 emulator, all I can say is "Not my decision." Thanks again!

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.
