Actually, the first bug is not only about &#233; but all entities from
&#128; to 
&#255; (except entities shared by both encodings)

About &&#233; not being decoded, you don't see it as a bug, right ?

There are two bugs here:

* There's a bug in PHP 5.2.14 in that it shouldn't decode &#233; when
the encoding is Windows-1251, as the character is not representable in
that encoding.
* There's a bug in both PHP 5.2.14 and PHP 5.3.3 in that &#233; is not
decoded when the encoding is ISO-8859-1.

Windows-1252 works fine in both versions.

Description:
------------
Hi,

There seems to be many bugs with html_entity_decode.

Using cp1252 encoding, it decodes HTML numeric entities as if encoding
was cp1251 
(please note that it works correctly on 5.3.3).
Using iso-8859-1 encoding does not seem to decode any numeric entity at
all (same 
situation in 5.3.3).

Please also note that &&#233; is never decoded neither on 5.2.14 nor on
5.3.3.

Test script:
---------------
html_entity_decode('&#233;&&#233; &#233; &#233;&amp;&#233;
&#233;&
&&#233;', ENT_NOQUOTES, 'cp1252');
html_entity_decode('&#233;&&#233; &#233; &#233;&amp;&#233;
&#233;&
&&#233;', ENT_NOQUOTES, 'cp1251');
html_entity_decode('&#233;&&#233; &#233; &#233;&amp;&#233;
&#233;&
&&#233;', ENT_NOQUOTES, 'iso-8859-1');

Expected result:
----------------
expected results :
&#233;&&#233; &#233; &#233;&&#233; &#233;& &&#233;
Ã©&Ã© Ã© Ã©&Ã© Ã©& &Ã©
Ã©&Ã© Ã© Ã©&Ã© Ã©& &Ã©

Actual result:
--------------
results in 5.2.14 :
Ð¹&&#233; Ð¹ Ð¹&Ð¹ Ð¹& &&#233;
Ã©&&#233; Ã© Ã©&Ã© Ã©& &&#233;
&#233;&&#233; &#233; &#233;&&#233; &#233;& &&#233;

results in 5.3.3 :
&#233;&&#233; &#233; &#233;&&#233; &#233;& &&#233;
Ã©&&#233; Ã© Ã©&Ã© Ã©& &&#233;
&#233;&&#233; &#233; &#233;&&#233; &#233;& &&#233;
