error read with useing QSettings

MLGDN

I use follow code to read ini file:

    QSettings settings(fileName, QSettings::IniFormat);
    settings.setIniCodec(QTextCodec::codecForName("utf-8"));
    settings.value("/Group/name", "default").toString();

the value in the file without comma is right, but it goes error when it contains , and the strange is if comma is under Chinese input method not English it is right. How to solve this problem?

@MLGDN Could you please explain better what the problem is?
Can you show the ini file you're trying to read?
And what error do you get?

@MLGDN Hi,friend. Welcome.

I think you should not set utf-8. In Qt5 is not to set, just like below:


    QSettings settings("test.ini", QSettings::IniFormat);
    //settings.setIniCodec(QTextCodec::codecForName("utf-8"));
    settings.setValue("key1","IamEnglish");
    settings.setValue("key2","I,am,English");
    settings.setValue("key3","我，是，中文");

    qDebug() << settings.value("key1","Default").toString();
    qDebug() << settings.value("key2","Default").toString();
    qDebug() << settings.value("key3","Default").toString();

and the ini file:

[General]
key1=IamEnglish
key2="I,am,English"
key3=\x6211\xff0c\x662f\xff0c\x4e2d\x6587

In the ini file, Qt used \x to encode Chinese.

@MLGDN
When there is a comma in value of ini file and if you read the value with a key, it will return a list.
settings.value("/Group/name", "default").toStringList(); will return an array of strings.
for eg. if you have

testKey=a,b,c,d in ini file and if you fetch value

qDebug() << settings.value("testKey","default").toStringList();

you will get
("a", "b", "c", "d")
