Question

Up until recently everything was working fine on my machines but since a few days I keep getting an error Encoding::UndefinedConversionError: U+2713 from UTF-8 to US-ASCII any time I post something from the browser to the server.

First since posts were involved I tried the most obvious thing with adding encoding to the database.yml:

development:
  adapter: postgresql
  hostname: localhost
  port: 5432
  username: mikael
  password:
  database: dev
  encoding: utf8

If I install ruby-debug19 and ruby-debug-base19 and run rails with:

rails s --environment=development --debug

Now everything is working fine. How the hell am I supposed to find out the cause of the problem so that I may fix it?

EDIT 1:

1.9.3p0 :001 > Encoding.default_internal
 => #<Encoding:UTF-8> 
1.9.3p0 :002 > Encoding.default_external
 => #<Encoding:UTF-8> 

EDIT 2:
If I run in production mode everything works fine.

Answer 1

This sounds like a bug that has been reported in Rails 3.1.2 has a workaround and the next release of 1.9.3 should fix the issue
