|
|
|
| 26 |
|

open($f, "<:encoding(foo)", "infoo"); |
| 27 |
|
|
open($f, ">:encoding(bar)", "outbar"); |

=head1 DESCRIPTION |
| 33 |
|
|
|
| 34 |
|
|
Open a filehandle with a transparent encoding filter. |
| 35 |
|
|
|
| 36 |
|
|
On input, convert the bytes expected to be in the specified |
| 37 |
|
|
character set and encoding to Perl string data (Unicode and |
| 38 |
|
|
Perl's internal Unicode encoding, UTF-8). On output, convert |
| 39 |
|
|
Perl string data into the specified character set and encoding. |
| 40 |
|
|
|
| 41 |
|
|
When the layer is pushed the current value of C<$PerlIO::encoding::fallback> |
| 42 |
|
|
is saved and used as the check argument when calling the Encodings |
| 43 |
|
|
encode and decode. |
