By the way, after months of trying all sorts of tricks to successfully encode the ÿ character to Hex in a UTF-8 encoded page, I realized that I had to initiate a Windows-1252 page first. And then it successfully converted the PNG to Hex. lol.
The NUL bytes (\x00) were problematic as well because unless they get loaded into a raw binary state, they usually get converted to spaces (20) . So I get it now. ITS A TEXT EDITOR! … but at least Windows-1252 gives me a work-around for bytes 0x00–0xFF
And then of course there’s Base64 to save the day!

Lastly, I copy and paste a lot of binary content , so thanks for IDM_EDIT_COPY_BINARY 42048
