I need to make a correction in regard to the actually provided length values:

a) The following assertions incorrectly hold:

static_assert( L""_len == 1, "Ouch");
static_assert( u""_len == 1, "Ouch");
static_assert( U""_len == 3, "Ouch");

b) For non-empty strings other "value patterns" occur, e.g. these tests

static_assert(L"1"_len == 3, "Ouch");
static_assert(u"1"_len == 3, "Ouch");
static_assert(U"1"_len == 7, "Ouch");

evaluate to true, even though the length should be 1 in all these cases.
