Is it possible to use big5 character set in Drupal?

A potential client of ours wants to use the big5 character encoding on their new website.

Is it possible to use the Drupal CMS to make a site in big5?

Its possible this questions does not make sense because I don't find many google results with big5 drupal as a keyword...

Pleas开发者_StackOverflow中文版e help!

I would say it is not possible. Not without hacking core and its database-layer, filtering-layer and form-layer.

Drupal passes all strings around in UTF-8. Big-5 is "included" in UTF-8, meaning: all characters in Big-5 can be found in UTF-8 (and many more).
