Incompatible character encodings: ASCII-8BIT and UTF-8

Rails
1

Hello,

I just tried to migrate one of my applications from ruby 1.8 to ruby 1.9
and get following error:
Showing app/views/layouts/application.html.erb where line #48 raised:
incompatible character encodings: ASCII-8BIT and UTF-8

48: <%= render :partial => ‘layouts/menu’ %>

I added “<%# coding: utf-8 %>” in application.html.erb and
layouts/_menu.rhtml but it still throws that error, anyone knows why?

I added “<%# coding: utf-8 %>” in application.html.erb and

<%# … %> is a comment, perhaps you meant <%-

No, all I found on google said I have to put it as a comment, <%- gives
a syntax error.

I just run into the same problem in two other projects. Is there a way
to set the encoding application wide?

You seem to have snipped the useful stuff. How about encoding rather
than coding? Though I am not convinced.

Sorry, that was a typo. Even though it’s still not working.

In every of my 4 projects with this error it always throws it when a
special char is being displayed like ä, ö , ü, é, à etc.

It would be cool if I just need to paste some “# encoding: utf-8” or
something somewhere and it recognizes everything as utf-8, is there
anything like that I could do?

I’ve been struggling with the same issue a few times, and the solution
that worked for me was to use a different mysql driver: ruby-mysql

in config/environment.rb:

config.gem ‘ruby-mysql’

or in Gemfile:

gem ‘ruby-mysql’

The encoding must also be set in config/database.yml:
adapter: mysql
encoding: utf8

Hey,

First of all thanks but I tried what you said and well…
gem install ruby-mysql
config/environment.rb: added config.gem ‘ruby-mysql’
config/database.yml: added adapter: mysql, encoding: utf8

But when I start the server I get following error:

You’re running:
ruby 1.9.1.378 at D:/ruby19/bin/ruby.exe
rubygems at D:/ruby19/lib/ruby/gems/1.9.1

Run rake gems:install to install the missing gems.

I of course tried rake gems:install but it didn’t help. I also tried to
just uninstall the mysql gem but that didn’t work either. Any idea?

I’m ran into the same problems after switching to Ruby 1.9.1. Have you
found a solution yet?

10

Any one knows what’s wrong?

11

Not yet, had to switch back to Ruby 1.8.6.

Maybe someone else has an idea?

12

That means if I do a “db:migrate:reset” (recreate the db with Ruby 1.9)
that error would disappear?

13

If you have have hard coded strings in ruby code you should try
Mystring =“bla bla”
Mystring.force_encoding(‘ASCII-8BIT’)
Before using it.
For database strings you should search for mysql to force encoding
(this is for db created with ruby 1.8)
Good luck

14

FYI: I execute these commands:
db:drop
db:create
db:setup

Still same error.

I tried it, no it doesn’t :frowning:

Most likely, you are outputting content stored in your DB as UTF-8 onto
a template that is ASCII. This fix works for me:
ruby_191_hacks.rb · GitHub – drop this into
config/initializers/ruby_191_hacks.rb. I posted more about upgrading to
1.9.1 here:

Are you sure you don’t have hard coded strings in the partial or
strings assigned
to variables through controller?

I’m only using I18n.t for strings and globalize2 for model translation.

Hi,

did You find a solution? I have the same problem on all of my projects.
DB in UTF8, rails in UTF8, but when it comes to partials with data with
german umlauts I get the mentioned error.

As far as I understand it’s a problem with the erb rendering engine that
forces ASCII encoding.

This encoding-thing is so digusting…

Greetings
