Invalid multibyte output after upgrading to rails 3 and ruby ​​1.9.2 - dtext = '[^ \\ x80]'

Question

I update my application from rails 2 to 3, and when I 'require' this file, which has an email address validator, I get an “invalid multibyte output” error:

dtext = '[^\\\\x80]'
pattern = /\A#{dtext}\z/

Any thoughts?

Answer 1

Try using:

pattern = /\A#{dtext}\z/, nil, 'n'

Modify the rfc822.rb file and change the addr_spec line to the following:

addr_spec = Regexp.new("#{local_part}\\x40#{domain}", nil, 'n')
