This is related to:
std::basic_string specialization and Circumventing template specialization
I tried the solution from std::basic_string specialization, but the problem is that CustomChar is a typedef for wchar_t and I have redefinition(conflict with specialization from std). How may I avoid usage of chart_traits when I'm not allowed to change CustomChar typedef?
回答1:
You could use Boost's/C++0x's disable_if to disable if there are known previous instantiations, like in the case of char and wchar_t.

This is the answer provided by Charles Bailey as a comment:
You can supply an alternative traits class (i.e. something other than a std::char_traits specialization) while still using wchar_t as the charT template parameter to std::basic_string
