QT6中的重音和特殊字符是否破裂？
我有一个QT程序，可以从CSV文件中读取并将信息保存到数据库中。 直到我尝试从QT 5.15.2更新到QT 6.3之前，没有问题。现在，当我从文件中阅读时，所有口音都会转换为问号。
我尝试使用几乎所有方法来明确解释QTEXTSTREAM或将QString文本转换为UTF-8或Unicode，它们都无法正常工作。这是QT 6中的一个已知问题（因为重音在QT 5.15.2中完美效果）吗？
提前致谢。
按照要求，这是读取CSV文件的片段：
QFile file(path);
file.open(QIODevice::ReadOnly | QIODevice::Text);
QTextStream in(&file);
while (in.readLineInto(&line)){
QStringList separatedLine = line.split("\t");
qDebug() << separatedLine;
//do things and save data in database
}
我遇到的问题是，如果我使用QT5.15.2编译，但在QT6.3.0中不使用它，则可以很好地工作。读取完全相同的.csv文件以下是删除：
//原始行
34111514 TARJETACOMUNICACIónTMB-251 TMB251
// QT 5.15.2 QDEBUG输出
Qlist（“ 34111514”，“ TarjetacomunicaciónTMB-251”，“ TMB251”）
// QT 6.3 QDEBUG输出
Qlist（“ 34111514”，“ Tarjeta comunicaci？n tmb-251”，“ TMB251”）
我非常怀疑CSV文件格式是否有问题，因为它在较旧的QT中可以正常工作。
I've got a Qt program that reads from csv files and saves the info into a database.
There was no problem until i tried to update from Qt 5.15.2 to Qt 6.3. Now, when I read from the files, all accents are converted to a question mark.
I've tried using pretty much every way to explicitly interpret a QTextStream or convert a QString text to Utf-8 or Unicode in general and they all failed to work. Is this a known issue in Qt 6 (because accents worked perfectly in Qt 5.15.2)?
Thanks in advance.
As requested here's the fragment that reads the csv files:
QFile file(path);
file.open(QIODevice::ReadOnly | QIODevice::Text);
QTextStream in(&file);
while (in.readLineInto(&line)){
QStringList separatedLine = line.split("\t");
qDebug() << separatedLine;
//do things and save data in database
}
The issue I have is that this works perfectly if I compile it with Qt5.15.2 but not in Qt6.3.0. Reading the exact same .csv file the following is debbuged:
//Original line
34111514 TARJETA COMUNICACIÓN TMB-251 TMB251
//Qt 5.15.2 qDebug outputs
QList("34111514", "TARJETA COMUNICACIÓN TMB-251", "TMB251")
//Qt 6.3 qDebug outputs
QList("34111514", "TARJETA COMUNICACI?N TMB-251", "TMB251")
I highly doubt it's a problem with the csv file formatting because it works fine in older Qt.

好的，经过几天的研究并尝试了现在的工作。我无法复制该问题，但是当我使用libreoffice calc来保存编码为UTF-8的CSV或通过电子邮件发送该文件时，一定发生了一些事情。
我想编码可能以某种方式变成或破坏了某些原因，出于某种原因，QT5.15.2可以解释，但是QT6.3不能。
我通过使用记事本++再次将文件编码为UTF-8来解决问题。
Okay so after a couple more days of research and trying things it now works. I cannot reproduce the issue but something must have had happened when I used LibreOffice Calc to save the csv encoded as UTF-8 or when I sent that file by email.
I suppose the encoding might have gotten in some way changed or corrupted into something that, for some reason, Qt5.15.2 could interpret but Qt6.3 couldn't.
I fixed the issue by using Notepad++ to encode the file as UTF-8 again.
