The program just outputs characters to its stdout. One way to see this
process is to redirect 'stdout' to a file:
$ my_program > my_output
Then, when you open file 'my_output' in a hex editor, you should see
that the program did output just a single char with value e.g. 132.
There are no other UTF-8 characters right after it, so I wouldn't expect
'τ' to be formed on the output.

They probably keep state for Unicode characters but don't reset it. (I
don't know whether they are required to.) Could you please try the
following program to see whether it prints τ for all tau arrays below?
import std.stdio;
import std.algorithm;
void main() {
char[][] taus = [ [ 207, 132 ],
[ 207, 0, 132 ],
[ 207, 'a', 132 ] ];
foreach (i, tau; taus) {
write(i, ": ");
tau.each!(write);
writeln();
}
}
For me, only the first one is a τ in a Unicode environment. You may see
3 taus under Terminal.

Not at all! I assume everybody here finds these topic very interesting
like I do. :)
