Binary and text are not on the same plane. Text is something a human can read. 
Binary is something a computer can read. For computers, text needs to be 
encoded as binary. Is Unicode binary or text? I think both. 

Even the distinction between text and images is very blurry. What is a glyph, 
a smiley, an emoji, an illuminated letter: text or image? I think those have 
features of both.

I can apply a textual algorithm to a PDF or SVG file that may contains both 
characters and outlines.
