NAME

       Cz::Cstocs - conversions of charset encodings for the Czech language

SYNOPSIS

               use Cz::Cstocs;
               my $il2_to_ascii = new Cz::Cstocs 'il2', 'ascii';
               while (<>) {
                       print &$il2_to_ascii($_);
               }

               use Cz::Cstocs 'il2_ascii';
               while (<>) {
                       print il2_ascii($_);
               }

               use Cz::Cstocs;
               sub il2toascii;
                       # inform the parser that there is a function il2toascii
               *il2toascii = new Cz::Cstocs 'il2', 'ascii';
                       # now define the function
               print il2toascii $data;
                       # thanks to Jan Krynicky for poining this out

DESCRIPTION

       This module helps in converting texts between various charset encodings, used for Czech and Slovak
       languages. The instance of the object Cz::Cstocs is created using method new. It takes at least two
       parameters for input and output encoding and can be afterwards used as a function reference to convert
       strings/lists.  Cz::Cstocs supports fairly free form of aliases, so iso8859-2, ISO-8859-2, iso88592 and
       il2 are all aliases of the same encoding.  For backward compatibility, method conv is supported as well,
       so the example above could also read

               while (<>) {
                       print $il2_to_ascii->conv($_);
               }

       You can also use typeglob syntax.

       The conversion function takes a list and returns list of converted strings (in the list context) or one
       string consisting of concatenated results (in the scalar context).

       You can modify the behaviour of the conversion function by specifying hash of other options after the
       encoding names in call to new.

       fillstring
           Gives alternate string that will replace characters from input encoding that are not present in the
           output encoding. Default is space.

       use_accent
           Defines whether the accent file should be used. Default is 1 (true).

       nofillstring
           When 1 (true), will keep characters that do not have friends in accent nor output encoding, will no
           replace them with fillstring.  Default is 0 except for tex, because you probably rather want to keep
           backslashed symbols than loose them.

       cstocsdir
           Alternate location for encoding and accent files. The default is the Cz/Cstocs/enc directory in Perl
           library tree. This location can also be changed with the CSTOCSDIR environment variable.

       There is an alternate way to define the conversion function: any arguments after use Cz::Cstocs that have
       form encoding_encoding or encoding_to_encoding are processed and the appropriate functions are imported.
       So,

               use Cz::Cstocs qw(pc2_to_il2 il2_ascii);

       define two functions, that are loaded into caller's namespace and can be used directly. In this case, you
       cannot specify additional options, you only have default behaviour.

ERROR HANDLING

       If you request an unknown encoding in the call to new Cz::Cstocs, the conversion object is not defined
       and the variable $Cz::Cstocs::errstr is set to the error message. When you specify unknown encoding in
       the use call style (like "use Cz::Cstocs 'il2_ascii';"), the die is called.
