Bug 18789 – std.stdio messes up UTF conversions on output

---- import std.stdio; void main() { // converting to char { auto f = File("test.txt", "w"); f.writeln("\U0001F608"w); // UTFException } // converting to wchar_t { auto f = File("test.txt", "w,ccs=UTF16LE"); // from char f.writeln("ö"); // writes garbage f.writeln("\U0001F608"); // ditto // from wchar f.writeln("\U0001F608"w); // leads to ErrnoException } } ---- PR follows.
