NAME

Unicode::RecursiveDowngrade - Turn off the UTF-8 flags inside of complex variable

SYNOPSIS

 use Unicode::RecursiveDowngrade;
 
 $rd = Unicode::RecursiveDowngrade->new;
 $var = {
     foo   => 'bar',
     baz   => [
         'qux',
         'quux',
     ],
     corge => \$grault,
 };
 $unflagged = $rd->downgrade($var);

DESCRIPTION

Unicode::RecursiveDowngrade will turn off the UTF-8 flag inside of complex variable in a lump. In spite of your intention, some modules turn it on every elements of returned variable. You may be hard up for turn them off if you don't need any UTF-8 flags in your variable. This module will fix it up easily.

Sometime I think about the UTF-8 flag is not stead. But some "XML::Parser" based modules will turn it on. For example, "XML::Simple" is really simple way to parse XMLs, but this module returns a simple hashref including flagged values. This hashref is very hard to use, isn't it?

METHODS

• new

  new() is a constructor method.

• filter

  You can set some filter to filter() accessor. The values of downgraded will be passed this filter function. You have to set a code reference to this accessor. Like this:

   use Unicode::RecursiveDowngrade;
   use Unicode::Japanese;
   
   $rd = Unicode::RecursiveDowngrade->new;
   $rd->filter(sub { Unicode::Japanese->new(shift, 'utf8')->euc });
   $unflagged = $rd->downgrade($var);
      

  the passed subref will be called inside downgrade() method.

• downgrade

  downgrade() returns a turned off variable of argument.

VARIABLES

•

$Unicode::RecursiveDowngrade::DowngradeFunc

This variable has a downgrade function for downgrade() method. You can override the variable for some other way.
