> People aren’t ASCII or UTF-8 machines; “e” and “E” are the same character
They are the same character to you, a native speaker of a Western language written in a latin script. They are the same to you because you are, in fact, an ASCII machine. Many many people in the world are not.
They are the same to me, they are different in ASCII, therefore I am not an ASCII machine. To me, the person using the computer to do work. Not the person wanting to do extra work to support the computer's internal leaky abstractions of data storage.
Your position, the position of too many people, is that I a native speaker of English etc. should not be allowed to have a computer working how English works because somewhere, someone else is different. This is like saying I shouldn't be allowed an English spell checker because there are other people who speak other languages.
