It's an old method. DOS days or before.
Windows generally still supports it, depending on the Edit-Form type.

Thanks again.

Hello CrashNBurn,

I don't know about the other application you mentioned, but I didn't know about ALT + numbers behavior. Both Windows Notepad and EmEditor insert the same symbols. I think that is the Windows behavior. Those are Unicode characters and that is why they can't be saved as ASCII. You can save them as a Unicode file. The other application assigns ALT+0x as inserting control characters (<20H). In EmEditor you can insert these characters from the Edit menu > Advanced > Insert Special Character. I hope this helps.

Thank you!

EmEditor cannot generate Alt+NumPad codes, 01 thru 08. The one that it CAN generate: ALT+10 - then causes EmEditor to refuse to save your file as ASCII - claiming data will be lost.

Whereas, for example, NotePad2 will generate Alt+NumPad codes.

Interestingly, I can copy the codes from NotePad2 into EmEditor -- which are then displayed as a graphic square and EmEditor will save the file without warning about data loss.
