Description:
------------
When using htmlentities() on data that has high position characters ( >127), the characters are translated into &amp;#nnnn; where nnnn is the character code.

It seems the characters are translated properly to &#nnnn;, and then the ampersand is translated into &amp;, making the translation of non ASCII characters pointless.

Reproduce code:
---------------
echo htmlentities("&#31169;&#12399;&#12460;&#12521;&#12473;&#12434;&#39135;&#12409;&#12425;&#12428;&#12414;&#12377;&#12290;&#12381;&#12428;&#12399;&#31169;&#12434;&#20663;&#12388;&#12369;&#12414;&#12379;&#12435;", ENT_QUOTES,'UTF-8');

Expected result:
----------------
&amp;#31169;&amp;#12399;&amp;#12460;&amp;#12521;&amp;#12473;&amp;#12434;&amp;#39135;&amp;#12409;&amp;#12425;&amp;#12428;&amp;#12414;&amp;#12377;&amp;#12290;&amp;#12381;&amp;#12428;&amp;#12399;&amp;#31169;&amp;#12434;&amp;#20663;&amp;#12388;&amp;#12369;&amp;#12414;&amp;#12379;&amp;#12435;&amp;#12290;
