I’ve tried both Courier New 10 and Lucida Console 10, the latter of which is used in Notepad. I can copy and paste from EmEditor to Notepad, and it shows up fine there.
It does show up in MS UI Gothic—but I need a monospaced font!
Strangely enough, it shows up fine in the EmEditor “Recently Used Characters” section in the “Insert Special Character” dialog.
Do you plan on giving us a better “Insert Special Character” dialog, by the way? I’d like something similar to Unipad.
