Milestone:  To Be Determined       |   Component:  regex      
  Version:  Boost 1.34.1           |    Severity:  Problem    
 Keywords:                         |  
-----------------------------------+----------------------------------------
 When using POSIX interface to boost::wregex [[:alpha:]] character class
 doesn't match non-ASCII alphabetical characters (eventhough C library's
 iswalpha() function correctly recognizes them).

 The attached program returns

 1
 0

 1
 1

 0
 1

 on Debian GNU/Linux ("Testing", Boost version 1.33.1). Changing:

 setlocale(LC_ALL, "en_US.utf8");

 to:

 std::locale en("en_US.utf8");
 std::locale::global(en);

 fixes the problem.
