      PROBLEM DESCRIPTION
      -------------------
      Java's x-windows-50220 and x-windows-50221 converter don't follow
      Windows' 50220 and 50221 specification on UDC/PUA

      Java: 1B244275211B2842
      Windows: 1B24427F211B2842

      public class c2b {
        public static void main(String[] args) throws Exception {
          int i = Integer.parseInt(args[1], 16);
          char[] ca = Character.toChars(i);
          System.out.print(Character.isDefined(i) ? " " : "*");
          for(char c : ca) System.out.printf("\\u%04X",(int)c);
          System.out.print(" -> ");
          for(byte b : (new String(ca)).getBytes(args[0])) System.out.printf("\\x%02X",(int)b&0xFF);
          System.out.println();
        }

      param($code, $hex)
      $enc_r = [Text.Encoding]::GetEncoding([int]$code)
      [char[]]$ca = @()
      $ca += ([System.Convert]::ToInt32([string]$hex, 16))
      $s = ""
      $enc_r.GetBytes($ca) | foreach {$s += [System.Convert]::ToInt32($_).ToString("X2")}
      $s
