NAME
       Encode::GSM0338 -- ESTI GSM 03.38 Encoding

SYNOPSIS
         use Encode qw/encode decode/;
         $gsm0338 = encode("gsm0338", $utf8);    # loads Encode::GSM0338 implicitly
         $utf8    = decode("gsm0338", $gsm0338); # ditto

DESCRIPTION
       GSM0338 is for GSM handsets. Though it shares
       alphanumerals with ASCII, control character ranges and
       other parts are mapped very differently, mainly to store
       Greek characters.  There are also escape sequences
       (starting with 0x1B) to cover e.g. the Euro sign.

       This was once handled by Encode::Bytes but because of all
       those unusual specifications, Encode 2.20 has relocated
       the support to this module.

NOTES
       Unlike most other encodings,  the following aways croaks
       on error for any $chk that evaluates to true.

         $gsm0338 = encode("gsm0338", $utf8      $chk);
         $utf8    = decode("gsm0338", $gsm0338,  $chk);

       So if you want to check the validity of the encoding,
       surround the expression with "eval {}" block as follows;

         eval {
           $utf8    = decode("gsm0338", $gsm0338,  $chk);
         };
         if ($@){
           # handle exception here
         }

BUGS
       ESTI GSM 03.38 Encoding itself.

       Mapping \x00 to '@' causes too much pain everywhere.

       Its use of \x1b (escape) is also very questionable.

       Because of those two, the code paging approach used use in
       ucm-based Encoding SOMETIMES fails so this module was
       written.
