Doc Bug #49939 iconv_substr() misbehaves when length parameter set to 0

Description:
------------
According to documentation and reflection: iconv_substr has third argument $length, default value is 0, but iconv_substr returns different result when argument is not passed and when argument is passed as zero. (Now it's not possible to call iconv_substr with $charset argument and preserve correct behaviour.)

Reproduce code:
---------------
var_dump(iconv_substr('foobar', 3)); // "bar"
var_dump(iconv_substr('foobar', 3, 0)); // ""
var_dump(iconv_substr('foobar', 3, NULL, 'UTF-8')); // ""

Expected result:
----------------
string(3) "bar"
string(0) "bar"
string(0) "bar"

Actual result:
--------------
string(3) "bar"
string(0) ""
string(0) ""

It's just a bug in the docs. iconv_substr() behaves exactly same way as substr() does with same parameters.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

Default is strlen($str).
