I don't see how that stackoverflow answer explains that this is not a bug.

Users should not get unicode errors from typical Blender usage.

Had seen a similar one recently, in chat. where the scene.render.filepath = "C:\Users\me\a" had to be changed to scene.render.filepath = r"C:\Users\me\a" in a python script.
Rushed over it here. Sorry.

@ankitm That's a different cause though, you have to escape backslashes in strings. The filepath from a bpy.types.BlendData object should be correctly formatted and encoded by Blender.

The error looks like the string is encoded with something other than UTF-8, like Windows-1252, and Blender tries to interpret the bytes as UTF-8.

This is a problem we ran into early on when moving to Python3.

File path properties of type: PROP_FILEPATH, PROP_DIRPATH, PROP_FILENAME use PyC_UnicodeFromByteAndSize which uses PyUnicode_DecodeFSDefaultAndSize as a fallback which is intended to handle this situation without raising an exception.

Please run this in the Python console and include the output here:

import sys
sys.getfilesystemencoding()
sys.getfilesystemencodeerrors()

I can't repro this on windows, what is the full path to the blend file on your system?

With the blend file that causes the error, could you show the output of this command in the Python console:

import bpy
print(bpy.context.blend_data.path_resolve("filepath", False).as_bytes())

There is seemingly a sub-folder with a really strange name in your one drive folder, if you want to export this model, i'd just make a directory called c:\temp copy your blend file there and export it. It still be nice to fix this issue, but if you need to export your model right now, that's how to do it.

The issue is caused by an invalid utf-8 encoding which isn't supported by surrogatepass, which is the default error handler on Windows.

This raises the question - why can't we use surrogateescape as Linux/MacOS do, I didn't see anything written down about why however I assume this is caused by NTFS using UTF-16.

Possible solutions:

Check if it's possible to set the file-system error handler to surrogateescape.
Use bytes for paths. Listing for completeness, not really practical to apply this to all file handling code.
Look into calling sys._enablelegacywindowsfsencoding(). Also not a good long term solution, noting this for completeness.

Further, checking Python 3.9 commits, there looks to be changes in this area, so it may require a Python version upgrade to resolve.

Marking this as a TODO.

While more graceful error handling would be good, how did we end up with an invalid utf-8 file path in the first place? Is there perhaps an error in how we convert Windows utf-16 to utf-8? Maybe a bug in our conversion function? Or something related to codepages that we don't take into account?

There was a report on #blender-coders about this error on a render farm, which may be related:

Exception in module register(): C:\Users\gatch\OneDrive\Ð”Ð¾ÐºÑƒÐ¼ÐµÐ½Ñ‚Ñ‹\SheepItCashe\sheepit\c289d82176a4a8beabe37ddaf5759516\2.91\scripts\addons\cycles\__init__.py

  target_path = _user_resource(resource_type, path)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc4 in position 28: invalid continuation byte

In this case we are retrieving a user configuration path, not reading it from a .blend file. That error seems like it should be reproducible, running Blender from the command line in a folder with certain special characters and perhaps with a particular system language configuration.

I'm still unable to repro this specific error, however putting blender in a folder called christmas time 🎅 (that's U+1F385 for the santa, it's a valid char) prevents blender from starting completely due to a long standing issue in BLI_strncpy_wchar_from_utf8 where assumptions are made on the size of whcar_t, may not be the same issue but i would not be surprised if it were real close.

I took a closer look at BLI_strncpy_wchar_from_utf8 and cannot phantom why we duplicated the code from BLI_str_utf8_as_utf32 here, given wchar_t is essentially UTF16 on windows. this function could just be

size_t BLI_strncpy_wchar_from_utf8(wchar_t *__restrict dst_w,
                                   const char *__restrict src_c,
                                   const size_t maxncpy)
{
#if WIN32
  return conv_utf_8_to_16(src_c, dst_w, maxncpy * 2);
#else
  return BLI_str_utf8_as_utf32(dst_w, src_c, maxncpy);
#endif
}

I feel like i'm missing something here, it surely cannot be this easy?! (this fix does allow blender to run from the christmas time 🎅 folder)

what am i missing?!

I think it may well be that easy. Likely just legacy code that never got replaced, or code that was developed and tested only on Linux.

I haven't found any reason to think that @LazyDodo's solution wouldn't work. Should work and be harmless. I think we should just commit that change and he and I can deal with any effects if they occur. Its not like any of us are going anywhere for Christmas. LOL

I did set the working directory to be mäh_Документы_cpu1

		new_env.put("BLENDER_USER_CONFIG", configuration.getWorkingDirectory().getAbsolutePath().replace("\\", "\\\\"));
		new_env.put("TMP", configuration.getWorkingDirectory().getAbsolutePath().replace("\\", "\\\\"));
		new_env.put("TEMP", configuration.getWorkingDirectory().getAbsolutePath().replace("\\", "\\\\"));

This cycles error seems to be Windows only and Blender 2.91 only.
I would hope for a corrective 2.91.1 release.

Ok, if it involves environment variables then that is a different issue than the one being fixed in D9822.

BLI_getenv needs to be modified to get a utf-16 string and convert that to utf-8.

I have a fix for BLI_getenv will post a small diff later today, that being said, neither of these two fixes would explain any of the breakage between 2.90 and 2.91 so that slightly concerns me

Are we sure it's actually 2.91 only, was the exact same thing tested in 2.90?

I'm going off what @Raimund58 is seeing, don't get me wrong the issues we found are valid and need fixing, they just don't explain terribly well why he is only seeing these issues on 2.91 given it's pretty old code we're mucking about in.

Well, the cycles error is after our logs only Blender 2.91, yes.
I found no logs where Cycles failed in a lower version.
And as far as I know we didn't change the script or the render command.
So yes, I think it is Blender 2.91 only. (And after I got a alpha build from @rjg to test it is also in Blender 2.92)

But we weren't able to reproduce it local. But I also didn't set the environments variables because I don't know how. :/

@brecht With the latest build from @rjg and the latest commit from @LazyDodo Cycles is again working for us!
Thank you all so much for your time <3

had some time to bisect this, the troubles start with 6f3a9031f7 but have not looked in depth what could cause the behavior we're seeing with 2.91

also given this ticket got filed about 6 months previous to that commit landing, it certainly cannot account for the issue in the opening post. So we have successfully muddied up this ticket with unrelated issues, in the future it is probably best to file a new ticket even if the symptoms seem similar .

There may still be a shared underlying cause though. BLI_strncpy_wchar_as_utf8 is used in the filebrowser, so it's possible that leads to an incorrect .blend file path as in the original description. D9822 would fix such a problem.
