Turn out the comment about overload into answer:

// For enum
template
typename std::enable_if::value, bool>::type
func(T& t, int x);

bool func(unsigned char& t, int x);

// for other
template
typename std::enable_if::value, bool>::type
func(T& t, int x);

// for other
template
typename std::enable_if::value, bool>::type
func(T& t, int x);

// specialization for unsigned char
template <>
bool func(unsigned char& t, int x);
