Fails to Detect UTF-8 without BOM

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Save a file in UTF-8 without BOM
2. Try to detect Character Encoding.

What is the expected output? What do you see instead?
I expect to see UTF-8 from the #getDetectedCharset() method. Instead I get null.

What version of the product are you using? On what operating system?
I am using juniversalchardet-1.0.3.jar on a Windows 7 System.

Please provide any additional information below.
When I use UTF-8 with BOM I can detect the file just fine but Java does not 
support BOM so I get characters at the beginning of the file which I do not 
want. Therefore I have been using UTF-8 without BOM.

Perhaps I am not feeding the detector enough data with the file I am reading 
in? Although I don't think that is the case because I have extended the amount 
of data inside of the file up to 171390 characters with no difference.

The problem may be, that your file does not contain any special characters 
(e.g. ä,ü,ß,...). In this case the library seems not to be able to detect 
the encoding.
