Question

I have tried a ton of stuff for instance:

Mechanize on Ruby 1.9.3 encoding issue and
How do I convert from a Mechanize::File object to a Mechanize::Page object?

But the error I keep getting is

.rvm/gems/ruby-1.9.3-p194/gems/mechanize-2.0.1/lib/mechanize/util.rb:59:in `encode': code converter not found (UTF-8 to UTF8) (Encoding::ConverterNotFoundError)

I have a class that uses mechanize and it works with ruby 1.8.7, but I need it to work with 1.9.3 because the rest of the rails app is in 1.9.3. Sorry I’m kind of clutter brained right now so if I need to include something else please let me know. This is also my first question on here.

Answer 1

The page you’re visiting may have incorrectly described its encoding.

I think the fix is change it yourself, by doing something like

page.encoding = "utf-8"
