Apache POI Abnormal spaces (Solved: \ u00A0 non-breaking space)

EDIT: Solved answer: was the indispensable space 00a0, not c0a0 non-destructive space.

After using Apache POI to convert from docx to plaintext and then reading plaintext in Java and trying to parse it, I ran into the following problems.

Output:

" "
first characterequals SPACE OR TAB 
false
[B@5e481248
[B@66d3c617
ARRAYTOSTRING SPACE: [32]
ARRAYTOSTRING ?????: [-62, -96]

      

        
        
        
      

    

For the code:

System.out.println("\t\"" + line.substring(0,1) + "\"\n\tfirst characterequals SPACE OR TAB \n\t" + (line.substring(0,1).equals(" ") 
                        || line.substring(0,1).equals("\t") ));
System.out.println(line.substring(0,1).getBytes());
System.out.println(" ".getBytes());
System.out.println("ARRAYTOSTRING SPACE: " + Arrays.toString(" ".getBytes()));
System.out.println("ARRAYTOSTRING ?????: " + Arrays.toString(line.substring(0,1).getBytes()));

      

        
        
        
      

    

String.trim () does not get rid of it
String.replaceAll ("\ s", "") does not get rid of it

I’m trying to parse a huge amount of document material and it’s turning into a major obstacle. I have no idea what is going on or how to interact with it, can anyone shed some light on what is going on here?
