<pre>When trying to read a unicode file, std::getline does not find newlines, i.e.,
something is broken when using std::getline after input.imbue(locale).
The code below should output "2 == 2", and it does so for libstdc++. libcxx
however ignores the newline and has the output "2 == 1", unless the newline
character is specified by hand.
Note that the deactivated part (#if 0) has the same problem, when the locale is
utf8.
#include <iostream>
#include <locale>
#include <sstream>
#include <string>
int main()
{
#if 0
std::locale locale("");
auto& input=std::wcin;
#else
std::locale locale("en_US.utf8");
std::wistringstream input(L"abc\r\nbca\r\n");
#endif
input.imbue(locale);
int count=0;
for(std::wstring s;std::getline(input,s /*,L'\n'*/ );++count);
std::cout << "2 == " << count << std::endl;
return count;
}</pre>
