I had filed the above bug report. As I had commented I suspected that the files pertaining to Inscript were affected. I examined the two files in/usr/share/eekboard/keyboards/symbols hi-inscript.xml & mr-inscript.xml The specific lines pertaing to the problem read: </key> <key keycode="48" name="AC11"> <keysym keyval="39">quoteright</keysym> <text category="letter">���</text> The problem is with the fourth line. I edited it to read as follows: <text category="letter">���</text> The problem was solved. The issue may be also there in other Inscript files. I hope this is helpful in resolving the bug. Thanking you
