In addition to Jonathan's list:

std::u16string // C++11
std::u32string // C++11

I would also find the following of interest (C++11):

typedef duration<signed integer type of at least 64 bits , nano> nanoseconds;
typedef duration<signed integer type of at least 55 bits , micro> microseconds;
typedef duration<signed integer type of at least 45 bits , milli> milliseconds;
typedef duration<signed integer type of at least 35 bits > seconds;
typedef duration<signed integer type of at least 29 bits , ratio< 60>> minutes;
typedef duration<signed integer type of at least 23 bits , ratio<3600>> hours;

and from <random>

typedef linear_congruential_engine<uint_fast32_t, 16807, 0, 2147483647>
minstd_rand0;

typedef linear_congruential_engine<uint_fast32_t, 48271, 0, 2147483647>
minstd_rand;

typedef mersenne_twister_engine<uint_fast32_t,
32,624,397,31,0x9908b0df,11,0xffffffff,7,0x9d2c5680,15,0xefc60000,18,1812433253>
mt19937;

ranlux24_base;

typedef subtract_with_carry_engine<uint_fast64_t, 48, 5, 12>
ranlux48_base;

typedef discard_block_engine<ranlux24_base, 223, 23>
ranlux24;

typedef discard_block_engine<ranlux48_base, 389, 11>
ranlux48;

typedef shuffle_order_engine<minstd_rand0,256>
knuth_b;

typedef implementation-defined
