Please help with codec in QSettings

[lni]

Hi,

I try to create an ini file using QSettings with utf8 codec, but I can' get key right regardless what I do. Please advise where I do wrong.

Thanks.

#include <QApplication>
#include <QSettings>
#include <QTextCodec>
#include <QDebug>
 
int main( int argc, char** argv )
{
  QApplication app( argc, argv );
 
  QTextCodec::setCodecForLocale( QTextCodec::codecForName( "utf8" ) );
 
  QSettings settings( "Test.ini", QSettings::IniFormat );
  settings.setIniCodec( QTextCodec::codecForName( "utf8" ) );
 
  settings.beginGroup( "LITH_SEC" );
 
  settings.setValue( QString::fromUtf8( "介壳灰岩" ), QString::fromUtf8( "灰岩" ) );
  settings.setValue( QString::fromLocal8Bit( "介壳灰岩" ), QString::fromLocal8Bit( "灰岩" ) );
  settings.setValue( "介壳灰岩", "灰岩" );
  settings.setValue( QString( "介壳灰岩" ).toUtf8(), QString( "灰岩" ).toUtf8() );
  settings.setValue( QString( "介壳灰岩" ).toLocal8Bit(), QString( "灰岩" ).toLocal8Bit() );
 
  settings.endGroup();
 
}

#include <QApplication>
#include <QSettings>
#include <QTextCodec>
#include <QDebug>

int main( int argc, char** argv )
{
  QApplication app( argc, argv );

  QTextCodec::setCodecForLocale( QTextCodec::codecForName( "utf8" ) );

  QSettings settings( "Test.ini", QSettings::IniFormat );
  settings.setIniCodec( QTextCodec::codecForName( "utf8" ) );

  settings.beginGroup( "LITH_SEC" );

  settings.setValue( QString::fromUtf8( "介壳灰岩" ), QString::fromUtf8( "灰岩" ) );
  settings.setValue( QString::fromLocal8Bit( "介壳灰岩" ), QString::fromLocal8Bit( "灰岩" ) );
  settings.setValue( "介壳灰岩", "灰岩" );
  settings.setValue( QString( "介壳灰岩" ).toUtf8(), QString( "灰岩" ).toUtf8() );
  settings.setValue( QString( "介壳灰岩" ).toLocal8Bit(), QString( "灰岩" ).toLocal8Bit() );

  settings.endGroup();

}

To copy to clipboard, switch view to plain text mode 

It produces the following file:

[LITH_SEC]
%U4ECB%U58F3%U7070%U5CA9=灰岩
%E4%BB%8B%E5%A3%B3%E7%81%B0%E5%B2%A9=ç<81>°� �¥Â²Â©
