Question

I believe this is OK, so I am creating a question that I have the answer to for other peoples benefit. The problem:

I’m using a remote link to send a request for information and returning script containing that information. The data that comes back is for some reason encoded in ISO-8859-15 even though I have done everything I could find that would make Rails & Ruby use UTF-8.

show.coffee

$('#messages_messages').html("<%= escape_javascript(render 'show') %>")
# _show.html.erb will create output with characters such as åäö

The response contains a bunch of ?-characters instead of åäö.

Answer 1

For some reason this bug only happens when using the .coffee filename. This is my solution:

Don’t use .coffee and the end of your filename.
show.js.erb

$('#messages_messages').html("<%= escape_javascript(render 'show') %>");
# _show.html.erb will create output with characters such as åäö

No encoding errors.
