Worked: 2.93
Short description of error
Blender saves the files but I can't see the thumbnails in the file manager if the file is saved inside a folder in which the name is written using accents. (Dolphin, in my case, not the file manager from Blender)
Exact steps for others to reproduce the error
Save any file of blender inside a folder named using accents like: vinícius
[Based on the default startup or an attached .blend file (as simple as possible)]

Hi, thanks for the report. File Preview is generating for me in 3.3
Did you set File preview type to None? You can check it from- {nav Edit > Preferences > Save & Load > Blend Files > File Preview Type}

No, friend, on any other folders Blender saves thumbnails perfectly. Even those files it did not save before. The file preview type was in "auto" and at the end, I left it on "camera view". I made a test creating new folders with names with and without accents and the problem is there where the accents are present and not where they aren't. I will test it with Blender 3.3.

I see what may be the problem here. I wrote what the problem was in the title but did not explain it properly in the description. I will edit that. I also forgot to specify what file manager I was talking about, and it is not the file manager from blender, but from the system, in my case, Dolphin.

Since Blender's file manager shows the previews, I imagine they are saved, but for some reason, Blender is unable to make them visible for Linux inside those folders.

Just made a test with Blender 3.3 and the problem is still present. Blender 3.1.2 also has the same problem. Blender 2.93.9 works as it should. There's no difference in the preview settings among them.

The problem is certainly related to the folder names. If I change the folder name from vinícius to vinicius all of them save the thumbnails properly in that folder. That Is not a huge problem since I know how to work around it. The big problem is that as I speak Portuguese I have many of my folder names with accents. My trees models folder, for example, is called árvores. It's complicated to restructure all my folder names structure affecting projects to which I already have models linked to.

I don't know if I am being clear enough. Sorry, English isn't my first language.

I made some editions in my comments to give some more information. Sorry, I don't know if you have seen them before or after the editions.

Hi, yes, I've seen your edits. I've reverted the status so other triagers can also check this.

I can confirm here on linux using Gnome's filemanager as well. Perhaps blender-thumbnailer, which is called by the shell to extract the thumbnail, is not reading the path correctly or is being passed an incorrect path to begin with.

normal vs. vinícius

Sorry, I've made a stupid comment due to the "incredible" search power of Dolphin with the file search enabled in the system settings. I didn't know how

I found "another bug" that I thought was something different, but finally, I've found out they are related somehow.

The problem is that only the compressed files are affected by this problem. If you save the files in folders with accents, but uncompressed, they work perfectly as they should.

Also, those compressed files have a problem when you save them anywhere and try to scale the thumbnails to a larger size, while the uncompressed blender files can be saved without any problem in any folder, including those that use accents. Without any rescaling problem.

I was already filling up a new bug report when I found that strange connection and thought that maybe this could help to find out where the problem is.

So, now we know that it affects only compressed files and have this secondary effect on folders that use accents.

Sorry, I forgot to send some prints of the problem. I also found out right now that if you rename an uncompressed file in the file manager the thumbnails stay unaffected, but if you do the same with a compressed file, the thumbnail disappears.

I also realized that, for some reason, the quality of the thumbnails of the compressed files is much better than of the uncompressed ones. I didn't figure out why.
