ASCII-8BIT and UTF-8 hell
#4684
MySQL drive does not recognize nor enforce UTF-8 encoding for Ruby 1.9. There is a problem with MySQL text and varchar fields for Rails3 and Ruby 1.9. They are not correctly encoded. Instead of UTF-8 they come as ASCII-8BIT, binary data, and when it is mixed with other UTF-8 text, Rails will raise an exception.
field = MyModel.first.field
field.encoding # => ASCII-8BIT
currently it has to dirty fix:
field = MyModel.first.field.force_encoding('UTF-8').encoding # => UTF-8
The patch enforce UTF-8 encoding for Active Record and MySQL.
