id probably just do

import std;

void main(){
	foreach(dchar c;stdin.byLineCopy.map!(a=>a.array).joiner){
		c.writeln;
	}
}

Everything will be fairly hacky

You need then stdin.readf!" %c"(x);
It worked for me with echo "123" | .\app.exe

But this is the simplest example. Support for different UTF symbols could require more work
