Considering that Pike's native double-quoted string type stored true
Unicode (not UTF-16, not eight-bit, the full Unicode range) back in
1998, you're quite correct in saying that some take on that task with
more enthusiasm than others. Of course, that exact same fact does tell
against your other and more important point, namely that people were
unable to speak non-English to each other until very recently. Good
luck.
