Reading a binary file to string variable does not populate correctly

Question

Hi, I am new to Adobe Air/Flex and I'm trying to read a
binary file which also contains text in "cleartext". The problem
I'm having is that when I call FileStream.readUTFBytes method, only
the first 6 characters are showing up in my string variable
"contents" when I debug it in FlexBuilder or use a trace command
and debug it. I have also tried with other types of files but I
have a similar problem unless it's a non-binary file.
Am I doing something incorrectly or should I be reading a
binary file differently than the way I'm reading it currently?
The source code is shown below.
TIA,
Magnus

It's difficult to tell what it is, it looks like a binary
pipe symbol but I can copy it from TextPad for example. Some of the
characters following it cannot be copied from TextPad which I
assume is because it's null. I can read the whole file in C#/.Net
and assign it to a string variable without any problems but perhaps
Air is somewhat limited to binary content.
