=head1 DESCRIPTION |
98
|
|
|
|
|
|
|
|
99
|
|
|
|
|
|
|
Plugin that offers method of converting character-code. |
100
|
|
|
|
|
|
|
|
101
|
|
|
|
|
|
|
The character-code is converted with L<Jcode>. |
102
|
|
|
|
|
|
|
|
103
|
|
|
|
|
|
|
The supported character-code is 'euc', 'sjis', 'utf8'. |
104
|
|
|
|
|
|
|
|
105
|
|
|
|
|
|
|
Please make the 'create_encode' method in the project, and return the object that |
106
|
|
|
|
|
|
|
does the code conversion from the method when converting it excluding L<Jcode>. |
107
|
|
|
|
|
|
|
|
108
|
|
|
|
|
|
|
sub create_encode { |
109
|
|
|
|
|
|
|
AnyComvert->new; |
110
|
|
|
|
|
|
|
} |
111
|
|
|
|
|
|
|
|
112
|
|
|
|
|
|
|
It sets it up so that all the input received with L<Egg::Request> is united by |
113
|
|
|
|
|
|
|
the character-code when 'character_in' is defined by the configuration of Egg. |
114
|
|
|
|
|
|
|
|
115
|
|
|
|
|
|
|
If it wants to treat the code not supported by this plugin, the code conversion |
116
|
|
|
|
|
|
|
can be done in that making the method in which '[code_name]_conv' in the project. |
117
|
|
|
|
|
|
|
And, when the [code_name] is set to 'character_in', the input united by a target |
118
|
|
|
|
|
|
|
code comes to be received. |

=head1 BUGS |
164
|
|
|
|
|
|
|
|
165
|
|
|
|
|
|
|
Jcode.pm is used and note the point that is always utf8 about the content, please |
166
|
|
|
|
|
|
|
if you do not receive the conversion result when the character to be converted |
167
|
|
|
|
|
|
|
into the method of *_ conv is passed by the SCALAR reference though it is not |
168
|
|
|
|
|
|
|
a translation of bug. |
169
|
|
|
|
|
|
|
This is because of being internally processed with utf8 in the specification of |
170
|
|
|
|
|
|
|
Jcode. |
171
|
|
|
|
|
|
|
|
172
|
|
|
|
|
|
|
my $text= 'test'; # For shift_jis. |
173
|
|
|
|
|
|
|
$e->euc_conv(\$text); # The content of $text is utf8. |
174
|
|
|
|
|
|
|
$text= $e->euc_conv(\$text); # The content of $text is euc. |
175
|
|
|
|
|
|
|
|
176
|
|
|
|
|
|
|
$e->utf8_conv(\$text); # This is untouched utf8. |
177
|
|
|
|
|
|
|
|
178
|
|
|
|
|
|
|
Perhaps, I think that it is a peculiar problem when L<Jcode> operates as Wrapper |
179
|
|
|
|
|
|
|
of L<Encode> module. |
