I created a page to document some international character issues within a GoDaddy subsystem and used the Arabic script numerals 0-thru-9 [٠١٢٣٤٥٦٧٨٩] as example chars. The page initially shows the correct chars on preview, but after saving and redisplaying, the view converts to ??????????. I tried editing and refreshing the page again with exactly the same result. I suppose it may not be a confluence app bug, but related to correct encoding in storage, which is the issue I was attempting to document with our systems.
