I have an rails application with an mySQL database and not the permission to change the database password of the user. The problem is that the password contains a mutated vowel like: asÖs8ss when I try to run rake db:migrate the migration fails with this error:

rake aborted!
special characters are not allowed

I tried to escape the Ö in this ways:

\xC3\x96
\u00D6

But this doesn’t help. I also added encoding: UTF8 to the database connection and #encoding: utf-8 to the top of the database.yml but nothing helps to solve my problem.

Has anyone an idea how to escape the Ö right or to fix this somehow?

UPDATE I am using JRuby, if this help?

    After I updated to the newest version of JRuby and run bundle update I got it to work. Also you have to make sure, all your files are utf-8 on my windows machine I had to configure my editor, because default was ANSI.

    I need to run db:migrate with this command:

    jruby -J-Dfile.encoding=UTF-8 -S rake db:migrate RAILS_ENV=production
