That clears things up. Thank you very much. Might I suggest the  
following modified doc snippet? Also, could you list what character  
set arguments are allowed, or link to a list of them?

P.S. I think PotgreSQL now creates databases in "UNICODE" by default.  
Am I correct in thinking that UTF-8 is a subset of UNICODE, therefore  
no conversion will need to happen on import?


<doc_snippet>
The -W option specifies the encoding of the input data (dbf file).  
When used, all attributes of the dbf are converted from the specified  
encoding to UTF-8. The resulting SQL output will contain a command to  
set CLIENT ENCODING to UTF-8, so that the backend will be able to  
reconvert from UTF-8 to whatever encoding the database is configured  
to use internally.
