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;

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.
