+
+bugprone-string-integer-assignment
+==================================
+
+The check finds assignments of an integer to ``std::basic_string<CharT>``
+(``std::string``, ``std::wstring``, etc.). The source of the problem is the
+following assignment operator of ``std::basic_string<CharT>``:
+
+.. code-block:: c++
+
+  basic_string& operator=( CharT ch );
+
+Numeric types can be implicitly casted to character types.
+
+.. code-block:: c++
+
+  std::string s;
+  int x = 5965;
+  s = 6;
+  s = x;
+
+Use the appropriate conversion functions or character literals.
+
+.. code-block:: c++
+
+  std::string s;
+  int x = 5965;
+  s = '6';
+  s = std::to_string(x);
+
+In order to suppress false positives, use an explicit cast.
+
+.. code-block:: c++
+
+  std::string s;
+  s = static_cast<char>(6);
