just wonder, is it required to use `std::string("one")` and one cannot use
merely "one"?

constructor is implicit, so it is not needed.

+  EXPECT_EQ(map.size(), 1);
+
+  map[u""_str] = std::string("null");
+  EXPECT_EQ(map.size(), 2);
+
+  auto entry = map.find(u"Foobar"_str);
+  EXPECT_TRUE(entry);
+
+  entry = map.find(u"Foobar2"_str);
+  EXPECT_FALSE(entry);
+
+  map[u"Foobar2"_str] = std::string("two");
+  entry = map.find(u"Foobar2"_str);
+  EXPECT_TRUE(entry);
+
+  map[u"Foobar3"_str] = std::string("three");
+  entry = map.find(u"Foobar3"_str);
+  EXPECT_TRUE(entry);
+
+  EXPECT_EQ(map.size(), 4);
+
+  map.erase(u"Foobar2"_str);
+
+  // DISABLED. This should be true, but it isn't
+  //EXPECT_EQ(map.size(), 2);

it should be compared against 3, not 2.

[hub, 2018/01/29 16:57:46]

forgot to change that one.

Done

+
+  entry = map.find(u"Foobar2"_str);
+  EXPECT_FALSE(entry);
+
+  int i = 0;
+  for (const auto& e : map)
+  {
+    EXPECT_FALSE(e.is_invalid());
+    // DISABLED entries that are deleted shouldn't be returned.
+    // See issue #6281
+    //EXPECT_FALSE(e.is_deleted());
+    i++;
+  }
+
+  EXPECT_EQ(i, 4); // SHOULD be 3. See issue #6281
+  EXPECT_EQ(i, map.size());
