Untwine fails if path contains Swedish characters

[mnoreke]

What is the bug or the crash?

When importing LAZ files into a point cloud, the import fails with an error of: Layer 19A004_616_42_7575: Untwine error: create_directory: The system cannot find the path specified.: "D:/QGIS/SjöboPointCloud/61_4/19A004_616_42_7575.copc.laz_tmp"

Changing "Sjöbo" to "Sjobo" resolves this issue.

Steps to reproduce the issue

Add layer of type PointCloud Select a file with "ö" in the file name Add layer

Supported QGIS version

New profile

• [ ] I tried with a new QGIS profile

Additional context

While I haven't tried a new profile, I have no idea how to create a custom one to start with. It's only day 2 of QGIS. :)

Weird, it should have been fixed long time ago... See https://github.com/qgis/QGIS/issues/41833

Confirmed using both QGIS 3.38.0 and QGIS 3.34.8 on Windows 10 (OSGeo4W). For example, with a tèst.laz file the following error is displayed: CRITICAL Layer tèst : Untwine error: Unable to open stream for 'C:/Users/Andrea/Downloads/tèst.laz' with error 'No error'

I found that as I was trying to figure out what was wrong. For some reason it didn't occur to me to link that issue, but I will blame my sleepy head at the time. :)
