System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: AMD Radeon R9 200 Series ATI Technologies Inc. 4.5.13586 Core Profile Context 20.1.3 26.20.15015.1007

Blender Version
Broken: version: 2.82 (sub 7), branch: master, commit date: 2020-03-12 05:06, hash: 375c7dc4ca
Worked: (optional)

Short description of error
Cache-folder name makes fluid simulation not working. My blend file (with fluid cache data) was in a folder named badeværelse and the fluid sim didn't work. Changed the folders name to badevaerelse and it worked.

Exact steps for others to reproduce the error
Make folder called "æ" (possibly "ø" and "å" too)
Make a blend file inside it and try to bake liquid sim and use the folder as cache directory for the fluid physics
See how no particles appear when you press bake

Cannot redo on macOS on f346fd3212
Can you try on a build from https://builder.blender.org
Also mention the filename tested.

This would be a Windows only bug, since macOS and Linux support UTF-8 by default.

Presumably there is some fopen or fstream usage in Mantaflow that needs to be fixed (see for example BLI_fopen).

I just tried this on Windows with the latest master but I am not able to reproduce the issue. There was a problem with filenames in the past (#73770) but that should be fixed.

@DanteTheDarant Can you please try to reproduce the issue with a daily build? If the issue persists, please also upload a simple .blend file.

Test.zip
I'm sorry I can't test a daily build. Don't know how to bake fluid data (like where is the button) in the new versions and I don't have to time to learn new things now (I know its probably written somewhere but exams)

I have uploaded a zip file with a simple setup in a folder named "TestÆ" (path: E:\TestÆ according to windows.. dunno how it handles the "Æ") . I can reproduce the error by storing the fluid cache folders in "testÆ".
If I change the folder where it stores the cache to for example E:\tempfiles everything works as normal.

Pictures included of the scenario described above.

@DanteTheDarant Thanks for the test file! On my end it seems to work fine. Question: When using "testÆ" as the cache directory, are there just no particles in the viewport or are there also no cache files being generated?

On a slightly related note, I discovered that having trailing whitespace characters in the cache directory gives a crash on Windows.

Also, it would be great if other people on Windows could test the issue with the latest master!

Mantaflow (fluid simulator) has no active developer at the moment. Moving those bugs as known issues so at least other users can find their issues already reported.
