Re: sring encode problem (hexadecimal)

[happy.barney]

search HTML::Entities docs, it looks to me that you are searching for this method:

encode_entities_numeric( $string, $unsafe_chars )

Hi happy.barney Thanks for the reply. Actaully i have test it in that way
but i am unluck to be returned an error
i cant figure out what happened
according to the doc i need to use
encode_entities( $string, $unsafe_chars )




 
#!/usr/bin/perl

use HTML::Entities;
$string="€";
$encoded = encode_entities_numeric($string, '<>&"');
print $encoded;


The error was read as :
Undefined subroutine &main::encode_entities_numeric called at 2.cgi line 5.
i was losted. i did the test in winxp.




Cheers

From the documentation of HTML::Entities:

       encode_entities_numeric( $string )
       encode_entities_numeric( $string, $unsafe_chars )
           This routine works just like encode_entities, except that t
+he
           replacement entities are always "&#xhexnum;" and never "&en
+tname;".
           For example, "encode_entities("r\xF4le")" returns "rô
+le", but
           "encode_entities_numeric("r\xF4le")" returns "rôle".

           This routine is not exported by default.  But you can alway
+s export
           it with "use HTML::Entities qw(encode_entities_numeric);" o
+r even
           "use HTML::Entities qw(:DEFAULT encode_entities_numeric);"

well. i am not so understand the doc as English is not my native language.
here is my code to test it again and it works .
It do produce string "€" start from "&#x" while it has 5 digits which is not 7 byte string .


 #use HTML::Entities;
use HTML::Entities"encode_entities_numeric";
$string="€";  # ("€"  expected out put result after encoding)
$encoded = encode_entities_numeric($string);

print $encoded;






while when i test it in this way

#use HTML::Entities;
use utf8 ; ###########
use HTML::Entities"encode_entities_numeric";
$string="€";  # ("€"  expected out put result after encoding)
$encoded = encode_entities_numeric($string);


print $encoded;

it print out character "€" itself as if there is no encoding happened.
what should i do??
