Hi Doug,

Thanks for the response. I do realize it's not the ideal situation, but it's
the database I inherited, so not much I can do there :) . I tried the
to_ascii and it doesn't seem to help much. It may be that I can try a
different client and get more legible characters. Not sure.

The lack of responses is prolly because this sort of thing is usually
handled by the client... The client for input should be stripping/converting
to ASCII/unicode whichever chars are unwanted and notifying the user if
anything is removed/unusable. The client for display should then be able to
parse the chars correctly...

You might be able to use your current data if you change your SELECT to
something like:

SELECT to_ascii(columnName, 'LATIN1') AS convertedColumn
	FROM tableName;
