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.
