<para>sprintf_iri is similar to sprintf and returns a new string formed by "printing" a variable number
of arguments arg_1 - arg_x according to the format string format. The difference is that the returned string is marked as being IRI string so some applications and clients may distinguish between RDF reference string and RDF literal.
</para>
<note><para>No matter what is the default server charset or default encoding of host OS, IRI strings are supposed to be in UTF-8 encoding so string arguments to print as well as the format itself are supposed to be UTF-8. Application may use calls of <link linkend="fn_charset_recode"><function>charset_recode</function></link> as arguments.</para></note>
