As a non-ascii person, by name and language, I find the clinging to an outdated character set quite off-putting. The consequences of this attitude is a source of annoyance and uncertainty every time I book an international plane ticket. Anything that can work to spread the acceptance and use of unicode is great in my book.
I have little sympathy or patience with the anti-unicode view, it’s a great improvement to code quality at a small price. Tools that cannot handle this should be abandoned. Someone struggling to interact with unicode in general is a red flag to me.
