[REG 5.9 -> 5.12.0] project doesn't compile if included file in resource has japanese characters in the name

If in the resource file of the project there are files with japanese characters in the name Qt Creators won't compile and return the following error (from the example attacched):

No rule to make target '../QmlTest/jo ?? ??.txt', needed by 'release/qrc_Sources_qmlcache.cpp'. Stop

It seem qmake generate the makefile by changing the japanese characters to '?' as it would be not able to manage unicode characters.

Older version fo Qt Creator was able to compile this project that it seem this bug has been introduced recently...

I made the test using MinGW and Android compiler, in both cases the problem occurs (as obvious since the problem is in the makefile generation phase).
