Типографика iText7 IndexOutOfBoundsException в тексте Bengli

Я пытаюсь создать PDF-файл текста Bengli с помощью iText7. Другой текст работает нормально, но один.

PdfFont font = null;
try {
     font = PdfFontFactory.createFont("SolaimanLipi.ttf", PdfEncodings.IDENTITY_H);
} catch (IOException e) {
     e.printStackTrace();
}    
Paragraph p = new Paragraph("ওয়ার্ড ২৭").setFont(font).setFontSize(18);
doc.add(p);

Я получаю ошибку:

Я использую iText 7.1.2 и typography 2.0.0. Любая помощь будет оценена по достоинству. Спасибо
