Re: Clean-room Engine.IO implementation committed to git 8.0/8.1

[Mirar @ Pike developers forum]

Strings with known encoding that can transfer into other strings with
a known encoding easily and readable (and in some cases without any
interaction) would be useful.

For instance,

Stdio.FILE x = ...;
x->set_encoding("utf8");

string s = "räksmörgås";
String t = String.JP2022("\33(BHello, world!");
x->write(s);
x->write(t);
x->write(s+t);
