Set UTF-8 as default string encoding in Heroku

Question

I need to change the default ruby string encoding to UTF-8 in Heroku. For some reason it is US-ASCII.

$ heroku console
Ruby console for myapp.heroku.com 
>> \"a\"         


        

Answer 1

As per the Heroku support staff, this is the magic thing:

heroku config:add LANG=en_US.UTF-8

Although heroku console will keep reporting strings encoding as ASCII-8BIT, your actuall app will be running with the correct encoding, based on the LANG config var. You can double check that by doing this:

$ heroku run bash
Running bash attached to terminal... up, run.2
u20415@022e95bf-3ab6-4291-97b1-741f95e7fbda:/app$ irb
irb(main):001:0> "a".encoding
=> #<Encoding:UTF-8>
