After a call to readln, the string returned has termination characters 
that need to be stripped off.

import std.stdio;
import std.file;

void main()
{
        string name = readln();

        while(name[$-1] == '\x0a' || name[$-1] == '\x0d')
                name.length -= 1;

        if(name.exists)
                writeln(name, " exists!");
        else
        {
                writeln(name, " doesn't exists!");
                return;
        }

        auto filearray = cast(char[]) read(name);
        writeln("\n", filearray);
}
