See the related, previous post.

Basically there are four places where encoding might be relevant:

- Did you create the database in utf-8 encoding? (probably yes)

- What is the nevironment of the server process? That is: what does the
  shell command 'locale' say when it is issued in the same environment
  as the server starts? (that is not necessarily the environment you get
  if you start a shell!). Try, e.g. putting ''export LANG=3Dus_US.UTF-8''
  just before the server is called (typically in /etc/init.d/postgresql
  or thereabout.

- What is your client's encoding (issue the SQL command ''SHOW
  CLIENT_ENCODING'' to learn about that (or ''SET CLIENT_ENCODING'' to
  change that)

- What is the locale of your client? (if it's on an unix-like system,
  see above. Otherwise I have no idea).

Hope that helps
