Specifies the return string mode for how Strings are to be returned for Perl hooks and scripts.
In the Local return string mode (CQ_RETURN_STRING_LOCAL), Strings being returned are first checked to ensure that they are in the local code page. If a String fails, an exception is thrown (caught with eval {} with the error in $@). Strings are always returned in the local code page.
In the Unicode return string mode (CQ_RETURN_STRING_UNICODE), no character checking on a String is performed. If the String being returned contains non-ASCII characters, it is returned in UTF8 format and not in the local code page.
