[bug] FeatureExtraction fails if the path to images contains a non-ASCII character

[xDEADC0DE]

Describe the bug FeatureExtraction fails with the message [14:14:50.784266][info] Job max memory consumption for one image: 825 MB if the path to images contains a non-ASCII character

To Reproduce Steps to reproduce the behavior:

1. Open Meshroom
2. Drag and drop photos from a folder with a non-ASCII character. I used E:\tést\photos
3. Save the project in the same folder as the photos, I used E:\tést\tmp.mg
4. Run the node FeatureExtraction
5. Get the error message

Expected behavior No error message. Doing the same steps as above with test instead of `tést´ works perfectly.

I discovered this solution thanks to this reddit post (from 7 months ago): https://www.reddit.com/r/photogrammetry/comments/196kjor/comment/khunkqg/

I’m guessing it is related to https://github.com/alicevision/Meshroom/issues/1988#issuecomment-1864630369 and will be fixed by https://github.com/alicevision/AliceVision/pull/1629

(apologies, I did look for open issues containing “ASCII” or “character” but the only one referencing this are closed)
