QString Unicode conversion

[user_mail07]

How do I convert QString to unicode code.I need to support asian language. I am using asian language kepyboard input.

So I have QString and I like to pass as std::string.

SetUserName(std::string);

QString strUser= "UserName";
//I have tried following:-

SetUserName(strUser.toUtf8().data());

I have also tried this:-

QTextCodec *codec = QTextCodec::codecForName("UTF-8");
QTextCodec::setCodecForCStrings(codec);

QTextCodec *codec = QTextCodec::codecForName("UTF-8");
QTextCodec::setCodecForCStrings(codec);

To copy to clipboard, switch view to plain text mode 

SetUserName(strUser.Ascii().data());

QString is internally unicode. You can access the characters individually as QChar's. I don't think std::string supports unicode?

what if I use wstring. Wstring supports unicode.
But still I don't get strUser.toStdWString().data())); to display right characters.

Have you considered toWCharArray?

This is exact issue I am having with foreign language:- When I tried to do UTf8() it get breaks:-

QString memo_text=textEdit.toPlainText();
 
      qDebug()<<memo_text; //Korean String value correct;
 
      QByteArray textTemp(memo_text.toUtf8() );
 
      qDebug()<<memo_text; //Korean String value incorrect; (weird characters) if I typed in korean 
 
      strcpy(memo_info->text , textTemp.data());
 
      qDebug()<<memo_text; //Korean String value incorrect;

QString memo_text=textEdit.toPlainText();
   
      qDebug()<<memo_text; //Korean String value correct;
  
      QByteArray textTemp(memo_text.toUtf8() );
  
      qDebug()<<memo_text; //Korean String value incorrect; (weird characters) if I typed in korean 

      strcpy(memo_info->text , textTemp.data());

      qDebug()<<memo_text; //Korean String value incorrect;

I found a solution. Actually I was not doing fromUtf8() conversion back while reading the value of string in human readable form. ToUtf8() gived encoded value.
