std::toupper(std::locale)

From Cppreference

Converts the character ch to uppercase if possible, using the conversion rules specified by the given locale's std::ctype facet.

[edit] Parameters

[edit] Return value

Returns the uppercase form of ch if one is listed in the locale, otherwise return ch unchanged.

[edit] Notes

Only 1:1 character mapping can be performed by this function, e.g. the uppercase form of 'ß' is (with some exceptions) the two-character string "SS", which cannot be obtained by std::toupper.

[edit] Equivalent function

template< class charT >
charT toupper( charT ch, const std::locale& loc ) {
    return std::use_facet<std::ctype<charT>>(loc).toupper(ch);
}
