Question

芬兰客户告诉我，芬兰语的正确（区域设置）排序是：a-z，å，ä，ö。

但是QString :: localeAwareCompare（）在Windows Vista的Qt 4.4.2中将其返回为：a，ä，å，b-o，ö，p-z。

#include <qapplication.h>
#include <qlocale.h>
#include <iostream>
#include <tchar.h>

int
main( int argc, char* argv[] )
{
    QLocale::setDefault ( QLocale( QLocale::Finnish ) );

    QApplication app( argc, argv );    

    QString s1 = "a";
    QString s2 = "ä";
    QString s3 = "å";
    QString s4 = "b";
    QString s5 = "o";
    QString s6 = "ö";
    QString s7 = "z";

    std::cout << "QString::localeAwareCompare( s1, s2 )=" << QString::localeAwareCompare( s1, s2 ) << "\n";
    std::cout << "QString::localeAwareCompare( s2, s3 )=" << QString::localeAwareCompare( s2, s3 ) << "\n";
    std::cout << "QString::localeAwareCompare( s3, s4 )=" << QString::localeAwareCompare( s3, s4 ) << "\n";
    std::cout << "QString::localeAwareCompare( s4, s5 )=" << QString::localeAwareCompare( s4, s5 ) << "\n";
    std::cout << "QString::localeAwareCompare( s5, s6 )=" << QString::localeAwareCompare( s5, s6 ) << "\n";
    std::cout << "QString::localeAwareCompare( s5, s6 )=" << QString::localeAwareCompare( s6, s7 ) << "\n";

    return app.exec();
}

输出：

QString::localeAwareCompare( s1, s2 )=-1
QString::localeAwareCompare( s2, s3 )=-1
QString::localeAwareCompare( s3, s4 )=-1
QString::localeAwareCompare( s4, s5 )=-1
QString::localeAwareCompare( s5, s6 )=-1
QString::localeAwareCompare( s5, s6 )=-1

我的芬兰客户得到的结果相同。这是一个错误还是我做错了什么？

我在Windows XP上测试了Qt 4.6.2中的代码，这些字符排序正确。在您的测试用例中，我得到以下输出：

QString::localeAwareCompare( s1, s2 )=-1
QString::localeAwareCompare( s2, s3 )=1
QString::localeAwareCompare( s3, s4 )=1
QString::localeAwareCompare( s4, s5 )=-1
QString::localeAwareCompare( s5, s6 )=-1
QString::localeAwareCompare( s5, s6 )=1

作为芬兰人，我可以确认您的客户对芬兰分拣订单是否正确。

那么也许你可以升级到新的Qt版本？

为什么QString :: localeAwareCompare（）没有正常工作
