Bug description:  mb_eregi finds space

Description:
------------
Sometimes mb_eregi finds space in the string when string in utf-8 and
contains Russian capitalized "Р" (chr(0xD0) . chr(0xA0) in utf-8,
it's not English "P").

Reproduce code:
---------------
<?php
        mb_internal_encoding('UTF-8');
        header('Content-Type: text/html; charset=utf-8');
        $x = '&#1055;&#1056;&#1048;&#1056;&#1054;&#1044;&#1040;'; //$x =
chr(0xD0) . chr(0x9F) . chr(0xD0) . chr(0xA0) . chr(0xD0) . chr(0x98) .
chr(0xD0) . chr(0xA0) . chr(0xD0) . chr(0x9E) . chr(0xD0) . chr(0x94) .
chr(0xD0) . chr(0x90);
        $r = mb_eregi('^([^[:space:]]+([[:space:]][ivx]+)?)(.*)$', $x, $m);
        print_r($m);
?>

Expected result:
----------------
Array
(
    [0] => &#1087;&#1088;&#1080;&#1088;&#1086;&#1076;&#1072;
    [1] => &#1087;&#1088;&#1080;&#1088;&#1086;&#1076;&#1072;
    [2] => 
    [3] => 
)

Actual result:
--------------
Array
(
    [0] => &#1055;&#1056;&#1048;&#1056;&#1054;&#1044;&#1040;
    [1] => &#1055;&#65533;
    [2] => 
    [3] => &#65533;&#1048;&#1056;&#1054;&#1044;&#1040;
)
