Notas
Algumas implementações são capazes de excluir qualquer faceta, incluindo os aspectos específicos da localidade com destruidores protegidas. Outras implementações requerem a faceta de ter um destruidor pública, semelhantes aos dos aspectos independentes de localidade de
<codecvt>. Original:
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 the locale-independent facets from
<codecvt>. The text has been machine-translated via Google Translate.
