Comment (by anonymous):

 You're right, doesn't really help :-(

 Try:

 {{{
 #include <boost/regex/icu.hpp>

 template <class C>
 void printout(const C& c)
 {
    for(unsigned i = 0; i < c.size(); ++i)
       std::cout << std::hex << (int)c[i] << " ";
    std::cout << std::endl;
 }

 int main()
 {
    using namespace boost;

    typedef u32regex::traits_type::string_type st;
    typedef boost::u8_to_u32_iterator<std::string::const_iterator, UChar32>
 conv_type;

    const std::string p = "[pq]\\.\\.[xy]";

    st t(conv_type(p.begin(), p.begin(), p.end()), conv_type(p.end(),
 p.begin(), p.end()));

    printout(p);
    printout(t);

    return 0;
 }

 }}}

 Which should output:

 {{{
 5b 70 71 5d 5c 2e 5c 2e 5b 78 79 5d
 5b 70 71 5d 5c 2e 5c 2e 5b 78 79 5d
 }}}

 Thanks!  John.
