Return true if s0 is less than s1 using case-insensitive comparison.
Defined in header <boost/url/grammar/ci_string.hpp>
bool ci_is_less( string_view s0, string_view s1);
The comparison algorithm implements a case-insensitive total order on the set of all strings; however, it is not a lexicographical comparison. The function is defined only for strings containing low-ASCII characters.
assert( ! ci_is_less( "Boost", "boost" ) );
