That's a property of your font and font rendering engine, not Unicode.
Sure. Hence "context". If you are e.g. trying to manually underline some
text in console output, for example in a compiler error message,
counting the number of characters will not actually be what you want,
even though it works reliably for ASCII text.
(Also, it's probably not quite six columns; most fonts I've tested, 漢字
are rendered as something like 1.5 characters wide, assuming your
terminal doesn't overlap them.)

It's precisely six columns in my terminal (also in emacs and in gedit).
My point was, how can std.algorithm ever guess correctly what you
/actually/ intended to do?
