When I create an executable file, it ends up looking like "ÿuàÿuØÿuÔè[þÿÿÄ".
I'm not sure where the binaries come in. Is this really binary, but 10100100 is
translated to e.g. ÿ in order to save disk space? Are there any good docs on this?

No, the text editor represents everything in ASCII (and or UTF-8), in which 8 bit sequences, or bytes (or characters), represent every letter. Therefore, ÿ is a series of 8 1's and 0's. If you want to see the actual binary, download a hex editor.

I get it, thanks a lot!
