QSring utf8 and latin1

[abhinav_oct30]

Hi,

I am using QT-5.
I have used the below code:

QString str1= QString::fromLatin1("abc÷ßà éöø");
QString str= QString::fromUtf8("abc÷ßà éöø");
if (str1==str)
        ui->textEdit_2->setText("true");
    else
        ui->textEdit_2->setText("false");

QString str1= QString::fromLatin1("abc÷ßà éöø");
QString str= QString::fromUtf8("abc÷ßà éöø");
if (str1==str)
        ui->textEdit_2->setText("true");
    else
        ui->textEdit_2->setText("false");

To copy to clipboard, switch view to plain text mode 

This always results in false.
Why is it like this?
Internally QString should be in same format,its character pointer which have different format,for which we use fromLatin1 or fromUtf8.

Why do you expect the result to be true?

You have two identical string literals containing non-ascii characters and pass them through two different codec functions.
Naturally you end up with two different results as each codec function interprets those non-ascii characters differently.

Which one of those is getting the correct interpretation depends on the encoding of your sources file:

if the source file is encoded in UTF-8, then the string literals is UTF-8, so fromUtf8() will generate the correct QString
