Description:
------------
HTML functions use encoding, not charset.

E.g. ISO-8859-1 is both character set and encoding but UTF-8 is encoding of Unicode character set.

There's also missing arg_info in get_html_translation_table().

I've already fixed Manual.


Test script:
---------------
Reflection::export(new ReflectionFunction('htmlspecialchars'));
Reflection::export(new ReflectionFunction('get_html_translation_table'));


Expected result:
----------------
Function [ <internal:standard> function htmlspecialchars ] {

  - Parameters [4] {
    Parameter #0 [ <required> $string ]
    Parameter #1 [ <optional> $quote_style ]
    Parameter #2 [ <optional> $encoding ]
    Parameter #3 [ <optional> $double_encode ]
  }
}

Function [ <internal:standard> function get_html_translation_table ] {

  - Parameters [2] {
    Parameter #0 [ <optional> $table ]
    Parameter #1 [ <optional> $quote_style ]
    Parameter #2 [ <optional> $encoding ]
  }
}



Actual result:
--------------
Function [ <internal:standard> function htmlspecialchars ] {

  - Parameters [4] {
    Parameter #0 [ <required> $string ]
    Parameter #1 [ <optional> $quote_style ]
    Parameter #2 [ <optional> $charset ]
    Parameter #3 [ <optional> $double_encode ]
  }
}

Function [ <internal:standard> function get_html_translation_table ] {

  - Parameters [2] {
    Parameter #0 [ <optional> $table ]
    Parameter #1 [ <optional> $quote_style ]
  }
}
