In case it matters: DrRacket stores its files as text when they contain only 
textual data, but when they contain non-textual data, e.g. pictures or 
graphical block comments, they’re stored in this format instead. To see this, 
try creating a file in DrRacket and then inserting a graphical comment box 
(Insert > Insert Comment Box), then save the file and examine it using another 
text editor.

Apologies if you already knew all of this.
