I was so pleased that the polyglossia package started supporting more languages, including Coptic. But when I try to invoke it with \textcoptic{} or the coptic environment, it typesets right-to-left, i.e. backwards. Interestingly, the problem doesn't seem to exist if \textcoptic{} is not invoked. Is there a reason for this, or was there a step I missed?<div>
