QCoreApplication::UnicodeUTF8 is deprecated

[hdd]

Found this :https://wiki.qt.io/Transition_from_Qt_4.x_to_Qt5
about this issue.

This gets raised, when trying to use compiled widget (pyside-uic....), which has the retranslateUi() .

QApplication::translate("Href_Gui", "Text:", 0, QApplication::UnicodeUTF8)

QApplication::translate("Href_Gui", "Text:", 0)

Not really sure how to tackle this down.

[hdd]

guess we can implement a mocked QApplication.UnicodeUTF8 property
and provide an override for PySide2/Qt5 on translate, so they can accept an argument more.

Thoughts ?

I've been opening a pull request : #99

Sorry to ask, but is this a problem you need solved? Or are you trying to cover all incompatibilities?

[hdd]

I'm porting a quite complex stack of code over Qt.py and it does use compiled ui ( designer-qt4 ) through pyside-uic , which by default sneak in the translate function.

Without this fix, any interface build with PySide/PyQt won't simply be loading, and error, and possibly make the app segfault.

Ah, excellent.

An example in the form of a test would be lovely to really drive this feature home.

[hdd]

thought the same, but I need #93 first .
So we can test both.

[mottosso]

#93 implemented.

[hdd]

tests are now available

For completeness, the missing piece of information is an example that illustrates the problem.

[mottosso]

Implemented in 0.5.0.

@hdd, let me know how this works for you!

Hi Marcus,
Does this solve also the UnicodeUTF8 Remapping issue on QApplication ?
(as it can't simply be ignored on old PyQt4/PySide code)

[mottosso]

Hey @hdd,

It solves it by compiling your .ui files with PySide2. That compiler won't produce references to this member.

[mottosso]

For completeness, the solution is to compile with PySide2-compatible compiler, and then either replace references to PySide2 with Qt, or automatically do so with --compile. See the release for details.
