C++ count matches regex function that works with both char and wchar_t?

Question

With the answer from this question I was able to create a function that uses regex to find and replace in strings that works with both char and wchar_t

Answer 1

std::regex_iterator is a class template too

template<typename CharT>
std::size_t countMatches(const CharT* find, const CharT* str)
{
    std::basic_string<CharT> text(str);
    std::basic_regex<CharT> reg(find);
    typedef typename std::basic_string<CharT>::iterator iter_t;
    return distance(std::regex_iterator<iter_t>(text.begin(), text.end(), reg),
                    std::regex_iterator<iter_t>());
}
