Bug description:Undocumented 5.6 BC Break: default encoding ISO-8859-1 -> UTF-8

Description:
------------
With PHP5.6 the default encoding changed from ISO-8859-1 to UTF8.
This bc break is not mentioned in the list of BC changes:

http://php.net/manual/en/migration56.incompatible.php

The charset related docs mention that 
    iconv.input_encoding
    iconv.output_encoding
    iconv.internal_encoding
    mbstring.http_input
    mbstring.http_output
    mbstring.internal_encoding
is deprecated as of 5.6 and we should use default_charset instead:
http://php.net/manual/en/ini.core.php#ini.default-charset

For non-utf8 legacy app which are updated to PHP5.6 it is not clearly
documented how the path is. just setting ini_set('default_charset',
'ISO-8859-1'); does not do the trick, because of the deprecated above
mentioned settings still default to UTF8.

It feels like non-utf8 apps can only be configured using deprecated
settings like (which does not work by the way)
       	        ini_set('default_charset', 'ISO-8859-1');
                iconv_set_encoding("internal_encoding", 'ISO-8859-1');
                iconv_set_encoding("output_encoding", 'ISO-8859-1');
                iconv_set_encoding("input_encoding", 'ISO-8859-1');

How is the correct way to migrate a non-utf8 app to 5.6? How should the
settings look like to be compatible to 5.5 defaults and also be future
proof (so dont rely on deprecated settings)?
Such a path should be documented in the migration guide.
