the string constructor does this for you.

+            return String();
+        if (!string.length())
+            return emptyString();

[esprehn, 2016/08/23 17:35:39]

ditto

+        return String(reinterpret_cast<const LChar*>(string.characters8()), string.length());
+    }
+    if (!string.characters16())
+        return String();

[esprehn, 2016/08/23 17:35:39]

ditto, you don't need to null check or empty check

[dgozman, 2016/08/24 00:45:00]

Done.

+    if (!string.length())
+        return emptyString();
+    return String(reinterpret_cast<const UChar*>(string.characters16()), string.length());
+}
+
+String toCoreString(std::unique_ptr<v8_inspector::StringBuffer> buffer)
+{
+    if (!buffer)
+        return String();
+    return toCoreString(buffer->string());
+}
