{‘locale’:‘en’} is fine, but If are supporting multiple language content in a column then mentioning only ‘en’ will be limitation right?

is it good to have index-case-insensitive for all text/string columns in a n-number of collection? It will not affect performance?

As for performance, it always depends of your use-case.

If the majority of your finds are case insensitive, it is probably more efficient to have your index insensitive. While it might be better to have a normal index when only few finds are case insensitive. Only profiling of your application can give you a definitive answer.
