The biggest problem with this "not the true text" issue is when coders encounter unicode.
A lot of coders, those who have worked in primarily english countries see ascii as utf-8 and the difference is invisible. They can go decades being oblivious to topics like encodings and mappings and display.
So it can be surprising to them when they start dealing with European characters for the first time. They view the text in one place (like an editor which treats the file as utf-8) and another (their program) which treats the text as ASCII.
It's hard to explain to them that "when I look at it" isn't a universal truth, it also matters how the "look at it program" chooses to interpret, and display, it.
