Comme un grand nombre d'opérations de regex sont sensibles aux paramètres régionaux (lorsque l'indicateur est réglé std::regex_constants::collate), la classe regex_traits détient généralement une instance d'une std::locale en tant que membre privé .
Original:
Since many of regex operations are locale-sensitive (when std::regex_constants::collate flag is set), the regex_traits class typically holds an instance of a std::locale as a private member.

std::regex_traits<char>
std::regex_traits<wchar_t>
Ces spécialisations permettent d'utiliser std::basic_regex<char> (aka std::regex) et std::basic_regex<wchar_t> (aka std::wregex), mais dans le but d'utiliser, par exemple, std::basic_regex<char32_t>, fourni par l'utilisateur std::regex_traits<char32_t> specializtion doit être défini .
Original:
These specializations make it possible to use std::basic_regex<char> (aka std::regex) and std::basic_regex<wchar_t> (aka std::wregex), but in order to use, for example, std::basic_regex<char32_t>, user-provided specializtion std::regex_traits<char32_t> needs to be defined.
