Ah sorry my bad. byLineCopy defaults to '\n' as line terminator 
so it worked on my system.

import std.algorithm;
File("data.txt", "r+")
     .byLineCopy(No.keepTerminator, '\r')
     .joiner(" - ")
     .writeln;

this will print the thing you wanted. If you want to capture that 
value in a variable then

auto result = File("data.txt", "r+")
                    .byLineCopy(No.keepTerminator, '\r')
                    .joiner(" - ");
