Proposed resolution:

1. In [basic.string], class template basic_string synopsis change as indicated:

   // 21.4.6 modifiers:
   ...
   basic_string& replace(const_iterator i1, const_iterator i2,
                         const basic_string& str);
   basic_string& replace(const_iterator i1, const_iterator i2,
                         const charT* s, size_type n);
   basic_string& replace(const_iterator i1, const_iterator i2,
                         const charT* s);
   basic_string& replace(const_iterator i1, const_iterator i2,
                         size_type n, charT c);
   template<class InputIterator>
     basic_string& replace(const_iterator i1, const_iterator i2,
                           InputIterator j1, InputIterator j2);
   basic_string& replace(const_iterator, const_iterator,
                         initializer_list<charT>);
   

2. In [string.replace] before p.18, change the following signatures as indicated:

   basic_string& replace(const_iterator i1, const_iterator i2, const basic_string& str);
   

3. In [string.replace] before p.21, change the following signatures as indicated:

   basic_string&
     replace(const_iterator i1, const_iterator i2, const charT* s, size_type n);
   

4. In [string.replace] before p.24, change the following signatures as indicated:

   basic_string& replace(const_iterator i1, const_iterator i2, const charT* s);
   

5. In [string.replace] before p.27, change the following signatures as indicated:

   basic_string& replace(const_iterator i1, const_iterator i2, size_type n,
                         charT c);
   

6. In [string.replace] before p.30, change the following signatures as indicated:

   template<class InputIterator>
     basic_string& replace(const_iterator i1, const_iterator i2,
                           InputIterator j1, InputIterator j2);
   

7. In [string.replace] before p.33, change the following signatures as indicated:

   basic_string& replace(const_iterator i1, const_iterator i2,
                         initializer_list<charT> il);
