I noticed Kobo eReader does not have Hebrew in pre-installed languages. Can kobo read Hebrew ePub properly?
Kobo eReaders have two reading engines:
- Adobe RMSDK (epub2)
- ACCESS NetFront (epub3)
The ACCESS NetFront epub3 engine supports RTL text in epub3 books with a .kepub extension. Depending on the model/firmware, you might have to embed/install Hebrew fonts. For more information also see this website.
You also might want to check out the Mobileread Kobo forum for more detailed information.
tl;dr The answer is yes, but you'll most likely have to convert epub2 books to epub3 books and change the file extension to .kepub. (You also might have to embed/install Hebrew fonts.)
