Encode::GSM0338 -- ESTI GSM 03.38 Encoding
240
use Encode qw/encode decode/;
241
$gsm0338 = encode("gsm0338", $utf8); # loads Encode::GSM0338 implicitly
242
$utf8 = decode("gsm0338", $gsm0338); # ditto
246
GSM0338 is for GSM handsets. Though it shares alphanumerals with ASCII,
247
control character ranges and other parts are mapped very differently,
248
mainly to store Greek characters. There are also escape sequences
249
(starting with 0x1B) to cover e.g. the Euro sign.
251
This was once handled by L<Encode::Bytes> but because of all those
252
unusual specifications, Encode 2.20 has relocated the support to
257
Unlike most other encodings, the following aways croaks on error
258
for any $chk that evaluates to true.
260
$gsm0338 = encode("gsm0338", $utf8 $chk);
261
$utf8 = decode("gsm0338", $gsm0338, $chk);
263
So if you want to check the validity of the encoding, surround the
264
expression with C<eval {}> block as follows;
267
$utf8 = decode("gsm0338", $gsm0338, $chk);
270
# handle exception here
275
ESTI GSM 03.38 Encoding itself.
277
Mapping \x00 to '@' causes too much pain everywhere.
279
Its use of \x1b (escape) is also very questionable.
281
Because of those two, the code paging approach used use in ucm-based
282
Encoding SOMETIMES fails so this module was written.
