Text::Iconv - Perl interface to iconv() codeset conversion function

       Michael Piotrowski <mxp@dynalabs.de>

       The Text::Iconv module provides a Perl interface to the iconv() function as defined by the Single UNIX
       Specification.

       The convert() method converts the encoding of characters in the input string from the fromcode codeset to
       the tocode codeset, and returns the result.

       Settings of fromcode and tocode and their permitted combinations are implementation-dependent.  Valid
       values are specified in the system documentation; the iconv(1) utility should also provide a -l option
       that lists all supported codesets.

   UtilitymethodsText::Iconv objects also provide the following methods:

       retval() returns the return value of the underlying iconv() function for the last conversion; according
       to the Single UNIX Specification, this value indicates "the number of non-identical conversions
       performed."  Note, however, that iconv implementations vary widely in the interpretation of this
       specification.

       This method can be called after calling convert(), e.g.:

         $result = $converter->convert("lorem ipsum dolor sit amet");
         $retval = $converter->retval;

       When called before the first call to convert(), or if an error occured during the conversion, retval()
       returns undef.

       get_attr(): This method is only available with GNU libiconv, otherwise it throws an exception.  The
       get_attr() method allows you to query various attributes which influence the behavior of convert().  The
       currently supported attributes are trivialp, transliterate, and discard_ilseq, e.g.:

         $state = $converter->get_attr("transliterate");

       See iconvctl(3) for details.  To ensure portability to other iconv implementations you should first check
       for the availability of this method using eval{}, e.g.:

           eval { $conv->get_attr("trivialp") };
           if ($@)
           {
             # get_attr() is not available
           }
           else
           {
             # get_attr() is available
           }

       This method should be considered experimental.

       set_attr(): This method is only available with GNU libiconv, otherwise it throws an exception.  The
       set_attr() method allows you to set various attributes which influence the behavior of convert().  The
       currently supported attributes are transliterate and discard_ilseq, e.g.:

         $state = $converter->set_attr("transliterate");

       See iconvctl(3) for details.  To ensure portability to other iconv implementations you should first check
       for the availability of this method using eval{}, cf. the description of set_attr() above.

       This method should be considered experimental.

       If the conversion can't be initialized an exception is raised (using croak()).

   HandlingofconversionerrorsText::Iconv provides a class attribute raise_error and a corresponding class method for setting and
       getting its value.  The handling of errors during conversion depends on the setting of this attribute.
       If raise_error is set to a true value, an exception is raised; otherwise, the convert() method only
       returns undef.  By default raise_error is false.  Example usage:

         Text::Iconv->raise_error(1);     # Conversion errors raise exceptions
         Text::Iconv->raise_error(0);     # Conversion errors return undef
         $a = Text::Iconv->raise_error(); # Get current setting

   Per-objecthandlingofconversionerrors
       As an experimental feature, Text::Iconv also provides an instance attribute raise_error and a
       corresponding method for setting and getting its value.  If raise_error is undef, the class-wide settings
       apply.  If raise_error is 1 or 0 (true or false), the object settings override the class-wide settings.

       Consult iconv(3) for details on errors that might occur.

   Conversionofundef
       Converting undef, e.g.,

         $converted = $converter->convert(undef);

       always returns undef.  This is not considered an error.

       The supported codesets, their names, the supported conversions, and the quality of the conversions are
       all system-dependent.
