Extended ASCII, that is. So, there are characters such as á, ű, ó and whatnot. Many people think that "lack of UTF-8" or "ASCII only" means there are no such characters.
There is no such thing as extended ASCII, as the standard only specifies characters up to 0x7F. What comes after is implementation dependent, DOS/Windows had code pages, there's ISO standards, SHIFT-JIS, etc. none of which are compatible with each other.
Glad to hear that. In that case text console in OpenBSD is not ASCII since I can pretty much both type and see those characters, right?! I mean, why say that it is ASCII-only if extended ASCII does not exist, yet those characters are displayed properly?
