Arabic text can be used in Boords storyboards. When you begin typing Arabic characters, the language will automatically be detected and it will read from right to left. Arabic can be added to the Storyboard Edit View and it can be downloaded as PDF files and as script exports (.docx files).
It’s possible to use a combination of both Arabic and English (or another left-to-right language) when both languages are in separate paragraphs. However, please note that it’s not possible to use both Arabic and English characters together in the same sentence.
