SAXParseException: character conversion error: Illegal character 0x9A...

Question

This is my problem:
I use JDom to parse remote XML document with DTD linked to it. But I get that error. Request is:
SAXBuilder builder = new SAXBuilder();
Document doc = builder.build(new URL(url));
This works fine when I use these XML and DTD docs locally, which means that I give xml file name as a parameter from console. Then everything goes well. But when I move my program to server and try to run it there, SAXParseException is thrown. Why???
Error is:
error on line 1 of document "http://server.net/doc.dtd" Character conversion error: Illegal ASCII character 0x9A (line number may be too low)
What this means? And why this just happens when I run program in server? Help, please

Exactly that's the problem.
String class :
* This class is implemented to map an ordinary java.lang.String
* into an xml compliant String
public class String2Xml
     private final String invalidChars [] = {"�",
                                                       "�",
                                                       "�",
                                                       "�",
                                                       "�",
                                                       "�",
                                                       "�",
                                                       "�",
                                                       "�",
                                                       "�",
                                                       "`",
                                                       "�",
                                                       "<",
                                                       ">",
     private final String replaceChars [] = {"��",
                                                       "&#223;",
                                                       "&#228;",
                                                       "&#246;",
                                                       "&#252;",
                                                       "&#196;",
                                                       "&#214;",
                                                       "&#220;",
                                                       "&#167;",
                                                       "&#128;",
                                                       "&#96;",
                                                       "&#180;",
                                                       "<",
                                                       ">",
                                                       "&apos;"};
     * Constructor
     public String2Xml();
     * This operation is implemented to check if the given String
     * matches one of the invalidChars. If an invalid char is found
     * it'll be replaced.
     * @return String - the correct xml String
     public String checkString(String check)
          for (int i = 0; i < invalidChars.length; i++)
               check = check.replaceAll(invalidChars, replaceChars[i]);
          System.out.println("Check : " + check);
          return check;
