Hi,
I was curious what the "high" four-byte ut8 unicode characters look like.
What typeface are you using to print them? Most type faces ("fonts") only
support a tiny portion of the Unicode range. For that matter, most of the Unicode range
is currently unused.
Why does the snippet below not print anything (well, it will eventually, I
think, but at that point I have lost my patience already). Puh-lease tell me
there are no such things as Mongolian, Chinese backspaces and other
nonprintable characters. ;-)
Chinese backspaces? Probably not. But there may well be unprintable characters
for all sorts of reasons:
- the font you are using simply doesn't have a glyph for the code-point;
- the code-point is not yet assigned, so there's nothing to show;
- the code-point represents an invisible character, like IDEOGRAPHIC SPACE, or
a zero-width character, like MONGOLIAN VOWEL SEPARATOR;
- or it represents a non-printing control character;
- or a formatting mark like LEFT-TO-RIGHT EMBEDDING;
- or it is one of the sixty-six guaranteed "non-characters", such as the
infamous byte-order marks U+FFFE and U+FFFF.
