QDesktopServices::openUrl() fails in Qt 6.8 on macOS for file paths with special characters ([, ])

PuskasAlex

I’ve encountered a regression in behavior when upgrading from Qt 5.15 to Qt 6.8 on macOS related to QDesktopServices::openUrl().

Working code in Qt 5.15:

QString x = "/Volumes/Untitled 99/testfolder1/test copy'[.txt";

QFileInfo fi(x);
qDebug() << "Exists:" << fi.exists() << ", isFile:" << fi.isFile();

QUrl url = QUrl::fromLocalFile(x);

bool ret = QDesktopServices::openUrl(url);
qDebug() << "RET:" << ret;

Output on Qt 5.15 (macOS):

Exists: true , isFile: true
RET: true

Same code fails in Qt 6.8:

list itemQFileInfo confirms the file exists
QUrl::fromLocalFile() generates a valid URL
But QDesktopServices::openUrl() returns false (Character [ appear to break the behavior)

There is any workaround?

Except creating a bug report (search before if there is already one) - compare the code between Qt5 and Qt6 - maybe you can spot the problem.
