Thanks, your suggestion seems to work. I'll had some unit tests and get in merge in the next couple of days.

Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> 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.

I did find the following on the ISO document: c) Any character that is not a regular character shall be written using its 2-digit hexadecimal code, preceded by the NUMBER SIGN only. ________________________________ Joao Andre Goncalves Customer Developer t | m 07733161880 [email protected] smartcommunications.com<https://www.smartcommunications.com/> [https://www.smartcommunications.com/wp-content/uploads/025_Trends2026-450x160_v1.jpg]<https://scale.smartcommunications.com/2026-Trends-White-Paper.html?utm_source=outlook&utm_medium=email&utm_campaign=wc-global-2026-white-paper-2026-trends> Explore the new era of AI-powered customer engagement.
