iphone - What are these Strange 'rogue characters' at the end of my NSString? -

I have a text file (songlist.txt) that retrieves my app from the server and stores locally when If I try to use the contents of the file in my app then I am getting unexpected results. When I looked into the issue, I came to know that strange characters were sometimes appearing at the end of the text file's NSSTING content.

Why are these funny characters? (Below is my source):

Example of Strange characters at the end of the string:

1) I
2) upp †
) Mul †
4) ID

// Text file exact content (songlist.txt)

Song Forest. Mp3
two songs MP3
Three song MP3
song four.m.pe. P.

It seems that the encoding is happening when you import encoding: Error: stringWithContentsOfFile attempts to use the method

  [NSString stringWithContentsOfFile: [[Self documentsDirectory ] StringByAppendingPathComponent: @ "music / songlist.txt"] Encoding: NSUTF8StringEncoding Error: Zero].  

Plus it leaves NSData step.
