My terminal is set to CP437 and uses a font incapable of rendering anything else.

Then again, I don't blindly pipe directly from the network into the shell either.

CP437 (the PC character set) has three blank spaces (although 0x00 is probably not going to be used), so 0xFF is displayed same as 0x20 so there is still a homoglyph.
