c语言unicode编码转换为汉字的函数

您可以使用以下函数将C语言中的Unicode编码转换为汉字：

wchar_t unicode_to_wchar(unsigned int unicode) {
    wchar_t wchar;
    if (unicode <= x7F) {
        wchar = (wchar_t)unicode;
    } else if (unicode <= x7FF) {
        wchar = (wchar_t)(((unicode >> 6) & x1F) | xC);
        wchar = (wchar << 8) | (wchar_t)((unicode & x3F) | x80);
    } else if (unicode <= xFFFF) {
        wchar = (wchar_t)(((unicode >> 12) & xF) | xE);
        wchar = (wchar << 8) | (wchar_t)(((unicode >> 6) & x3F) | x80);
        wchar = (wchar << 8) | (wchar_t)((unicode & x3F) | x80);
    } else if (unicode <= x10FFFF) {
        wchar = (wchar_t)(((unicode >> 18) & x07) | xF);
        wchar = (wchar << 8) | (wchar_t)(((unicode >> 12) & x3F) | x80);
        wchar = (wchar << 8) | (wchar_t)(((unicode >> 6) & x3F) | x80);
        wchar = (wchar << 8) | (wchar_t)((unicode & x3F) | x80);
    }
    return wchar;
}

此函数将Unicode编码转换为wchar_t类型的汉字。
