your database encoding is UTF8 ? the language or environment you're
using to generate those strings such as 'acząčž' is also UTF8 ?
postgresql supports UTF-8 unicode just fine. It does not directly
support the bastardized UTF-16 'unicode' implemented by Windows NT and
derivatives (2000, XP, 2003, Vista, 2008, 7), but on those platforms it
generally behaves fairly sanely as long as you realize UTF8 is its
native tongue.
of course, the database has to be created as a UTF8 database, its
possible to initialize the server cluster in "C"/"POSIX"/"SQLASCII"
which says bytes-are-bytes and encodings are unknown, or in various 8
bit encodings like LATIN-1.
