javaIf you've ever run into problems faced with multi-lingual text differences, Jason's latest article will solve just that.  Learn how to make use of Unicode character-sets when developing in a J2ME-based environment, where you'll more than likely have a need to develop MIDlets in multiple languages.

J2ME and Unicode - Read Unicode File
(Page 4 of 6 )

The next step in module code separation would be to load language definitions from an external source.  One option would be to read in language definitions from a text file, more appropriately a Unicode file.  Here is a method you can use to read a Unicode text file:

To create a test file you can use the free application, Simredo, from http://www4.vc-net.ne.jp/~klivo/sim/simeng.htm


   public String readUnicodeFile(String filename) {
     StringBuffer buffer = null;
     InputStream is = null;
     InputStreamReader isr = null;
     try {
       Class c = this.getClass();
       is = c.getResourceAsStream(filename);     
       if (is == null)
         throw new Exception("File Does Not Exist");
       
       isr = new InputStreamReader(is,"UTF8");     
     
       buffer = new StringBuffer();
       int ch;
       while ((ch = isr.read()) > -1) {
         buffer.append((char)ch);
       }      
       if (isr != null) 
         isr.close();              
     } catch (Exception ex) {
       System.out.println(ex);
     }
     return buffer.toString();      
   }
