In want a result as i write in a comment, with remove unwanted

import std.stdio;

void main() {
        auto fichier = File("values.txt", "r+");
        string[] buffer;
  foreach (line ; File("values.txt").byLine)
    buffer ~= line.to!string;

  writeln(buffer);
  // Result: ["abcd\r", "1234\r", "03b52h"]

  writeln(buffer[0], " - ", buffer[1], " - ", buffer[2]);
  // Result:  - 03b52h    :-(

  // Instead, i would :  abcd - 1234 - 03b52h  !!!

executeShell("pause");
fichier.close();
}

Thanks a lot, by advance :-)

void main() {
    File("data.txt", "r+")
        .byLineCopy()
        .array()
        .each!writeln;
}

byLineCopy removes the new lines. If in the future you would need 
the new line symbol call byLineCopy(Yes.keepTerminator)
