UTF-8 在 Ruby on Rails 中的问题

Question

I'm trying to display pieces of text in multiple languages. Because they're all European languages i've chosen to stick with UTF-8 encoding for the database and the sources of the data. The Database is MySQL and setup with UTF-8 encoding.

When looking at the configuration of my RoR project, I can find various settings that tell it to do everything in UTF-8 encoding. The data I've stored in the database comes from an XML file that has the UTF-8 encoding attribute and is created with notepad++ and saved with UTF-8 encoding.

When I retrieve the data from the database however, the output is text withs everal � entities in it. I'm clueless on how to solve this problem.... Below is my environment setup:

$ gem env
RubyGems Environment:
  - RUBYGEMS VERSION: 1.5.2
  - RUBY VERSION: 1.8.7 (2011-02-18 patchlevel 334) [i386-mingw32]

  - REMOTE SOURCES:

If there's anything else needed of info, please ask and i'll update this topic. I'm just trying to get the data to be displayed properly.

All your database configuration seems fine, did you check if your browser isn't forcing any charset encoding? Try changing the charset manually in your browser.

Also, check your html files to find any other charset encoding that isn't utf8
