Rails: UTF-8 encoding issue with mailer and text partials

Question

I am building a Rails application and am face of a problem with my text mailer: I can’t find how to make special character (é, è, à, …) to be encoded properly.
It works grea

Answer 1

I finally found my issue. It was coming from the inky-rb gem which has some problem to understand encoding.

I just rename my layout (or template) like this:

# app/views/layouts  
default.text.inky # => default.text.erb
