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 always 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.
