Description:
------------
str_word_count return wrong number, if char "я" is
contained in the word.

Problem code (in file ext/standard/string.c):
while (p < e && (isalpha(*p) || (char_list && ch[(unsigned char)*p]) || *p == '\'' || *p == '-')) {

Corrected code:
while (p < e && (isalpha((unsigned char)*p) || (char_list && ch[(unsigned char)*p]) || *p == '\'' || *p == '-')) {

Description of bug fixes in Russian language:
http://phpclub.ru/talk/showthread.php?postid=746475#post746475

Reproduce code:
---------------
<?php
setlocale(LC_ALL, 'ru_RU.cp-1251', 'ru_RU.CP1251');
var_dump(str_word_count('&#1088;&#1091;&#1089;&#1089;&#1082;&#1080;&#1081; &#1090;&#1077;&#1082;&#1089;&#1090;. &#1103; &#1090;&#1077;&#1089;&#1090;&#1077;&#1088;. &#1072;&#1103;&#1073;&#1072;&#1075;. &#1103;&#1072;&#1087;. &#1072;&#1074;&#1103;', 2));
?>

  [32]=>
  string(3) "&#1103;&#1072;&#1087;"
  [37]=>
  string(3) "&#1072;&#1074;&#1103;"
}
