I have been using emacs for almost 7 years now. Started with emacs 23. I have used to read and write tamil language text inside emacs with both scim-input and ibus under gnome without any additional config inside emacs. But after switching to emacs 25 the system input is not working and even inside if I select tamil-itrans input methods, I cannot type in tamil text.
Even tamil script rendering has been degraded. What can I do to rectify this??
