~wbuffer_convert(); |  |

Destroys the `wbuffer_convert` object and deletes `cvtptr`﻿.

### Notes

Some implementations are able to delete any facet, including the locale-specific facets with protected destructors. Other implementations require the facet to have a public destructor, similar to the locale-independent facets from `<codecvt>`.

### Example

Run this code

    #include <codecvt>
    #include <iostream>
    #include <locale>
    #include <utility>

    // Utility wrapper to adapt locale-bound facets for wstring/wbuffer convert
    template<class Facet>
    struct deletable_facet : Facet
    {
        template<class... Args>
        deletable_facet(Args&&... args) : Facet(std::forward<Args>(args)...) {}
        ~deletable_facet() {}
    };

    int main()
    {
    // GB18030 / UCS4 conversion, using locale-based facet directly
    //  typedef std::codecvt_byname<char32_t, char, std::mbstate_t> gbfacet_t;
    // Compiler error: "calling a protected destructor of codecvt_byname<> in ~wbuffer_convert"
    //  std::wbuffer_convert<gbfacet_t, char32_t>
    //      gbto32(std::cout.rdbuf(), new gbfacet_t("zh_CN.gb18030"));

    // GB18030 / UCS4 conversion facet using a facet with public destructor
        typedef deletable_facet<std::codecvt_byname<char32_t, char, std::mbstate_t>> gbfacet_t;
        std::wbuffer_convert<gbfacet_t, char32_t>
            gbto32(std::cout.rdbuf(), new gbfacet_t("zh_CN.gb18030"));
    } // destructor called here
