Why does encode
delete the passed argument, if CHECK
is set to a true value?
#!/usr/bin/env perl
use warnings;
use strict;
use utf8;
use Encode;
my $decoded = 'h';
if ( eval { encode( 'utf-8', $decoded, 1 ); 1 } ) {
print "|$decoded|\n"; # prints ||
}
The encode () method encodes the string, using the specified encoding. If no encoding is specified, UTF-8 will be used. Optional. A String specifying the encoding to use.
If no encoding is specified, UTF-8 will be used. Optional. A String specifying the encoding to use. Default is UTF-8 Optional.
Python String encode () Method 1 Definition and Usage. The encode () method encodes the string, using the specified encoding. If no encoding is specified, UTF-8 will be used. 2 Syntax 3 Parameter Values. A String specifying the encoding to use. A String specifying the error method. 4 More Examples
The file is checked into source control in an encoding that is different from what VS Code or PowerShell expects. This can happen when collaborators use editors with different encoding configurations. Often encoding errors present themselves as parse errors in scripts.
It is for use in the case where you are repeatedly passing chunks of data to encode
or decode
. The idea is that the function will remove the part of the string that it has translated, and you need only append the next chunk to what is left. It is useful for handling multi-byte encodings that may be split across two chunks.
If you don't want this behaviour then you can OR the Encode::LEAVE_SRC
bit into the third parameter. Like this
use utf8;
use strict;
use warnings;
use Encode qw/ encode decode FB_CROAK LEAVE_SRC /;
use Data::Dump;
my $decoded = 'ABC';
dd $decoded;
my $encoded = encode( 'UTF-8', $decoded, FB_CROAK | LEAVE_SRC );
dd $decoded;
dd $encoded;
output
"ABC"
"ABC"
"ABC"
