Re: Font names using multi-byte strings

I was able to get the same name and I suggest this method:
1- Translate the string to UTF-8 bytes representation.
2- Get the bytes and encode them instead of characters.

This way the UTF-8 statement should be respected.
In code (beware: not efficient and without error management):

in escapeName of PDFName:

   byte[] characters ;
 // get UTF-8 bytes
   try {
        characters = name.substring((skipFirst ? 1 : 0)).getBytes("UTF-8");
      } catch (UnsupportedEncodingException e) {
          throw new RuntimeException("Invalid Name:"+name);
      }

// encode bytes
        for (int i = 0, c = characters.length; i < c; i++) {
        int ch = (0x00FF&characters[i]);

            if (ch < 33 || ch > 126 || ESCAPED_NAME_CHARS.indexOf(ch) >= 0)
{
                sb.append('#');
                toHex(ch, sb);
            } else {
            char cxc = (char)ch ;
                sb.append(cxc);
            }
        }
        return sb.toString();

where toHex() manages an int

Best regards.
