Opening files with Polish diacritic signs doesn't work on Windows

[marmistrz]

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
The following is done on a Windows 7 machine.

1. Take a .dcm file containing a Polish diacritic sign, for instance Rafał.dcm
2. Double click the .dcm file in Windows explorer to open it in Weasis.

Expected behavior
The image loads (this is actually the behavior on Linux)

Actual behavior
No image loads. The same happens if I run Weasis through cmd as Weasis.exe Rafał.dcm. If the file is renamed not to contain the ł letter, the image loads as expected.

Desktop (please complete the following information):

• OS: Windows 7
• Java Rutime: 1.8.0_131
• Weasis Version: 3.6.0

Additional context
If the image is manually imported through the "import" menu, the image is successfully loaded.

Traces
I don't know how to get logs on Windows. There are no logs printed when the app is run from cmd 😕

I managed to reproduce the issue. This happens when the path in go through the binary (built by jpackage).

I've submit a bug report in the openjdk project.

JRE 8 is pretty old, maybe using a newer version would do the trick? (I don't have access to the machine ATM so I can't test it right now)

No Weasis native embeds the modular JDK 14 (the latest release).

Fix in JDK 15
