Concerning the character ꝛ Hi. I am creating an epub version of a book, which contains the character above. In iBooks (v1.15) on the desktop (High Sierra) the character is displayed like this: However, the correct character is not displayed when the same epub book is viewed within Apple's iOS Books app. Instead, a placeholder is shown. Would anyone happen to know why this is? I'll try to upload a screenshot from iOS later. Thank you.
