Brailling In Spanish Using iOS 13

Hello, I am using the Duolingo application to learn Spanish. I am using an iPhone 10 running iOS 13.1.3. I have paired my phone with an Orbit 20 Braille notetaker. To be able to write grade 1 Spanish in this application, I am using the Spanish Liblouis Braille table. Using this table, I am unable to write a questionmark. The Spanish questionmark in Braille is the "en" sign = dots 2-6. The LibLouis library interprets this symbol as a numeric 5. How do you write a Spanish questionmark in Braille using this library? Thanks.
