I recently changed my system language to Tamil (a language used in India) from English. While I was enjoying Ubuntu in Tamil, my favorite editor vim has run into an issue because of the system language change, it seems.
How can I fix this?
I would try running this in from the vim terminal while the offending file is opening
and if that doesn't work, you should be able to find what you need here Vim User Manual Language Encoding
What happens if you run vim from the terminal and not gvim?
