vcpkg’s Error message:

```auto
Command failed: D:/Coding/vcpkg/downloads/tools/cmake-3.31.10-windows/cmake-3.31.10-windows-x86_64/bin/cmake.exe -E tar xjf D:/Coding/vcpkg/downloads/microsoft-onnxruntime-v1.23.2.tar.gz

```

See the related issue [here](https://github.com/microsoft/vcpkg/issues/48699)

And if you search ‘tar xjf’ in vcpkg’s issue list, you can see many similar [issues](https://github.com/microsoft/vcpkg/issues?q=is%253Aissue%20tar%20xjf).

Any ideas?

‘j’ is for bzip2, why is that used for a .tar.gz?

I have found the cause:  
In the tar.gz file, there is a folder named `microsoft-onnxruntime-v1.23.2.tar.gz\onnxruntime-1.23.2\winml\test\collateral\models\UnicodePath\こんにちは maçã`.

If you extract it directly from the console using `tar xjf microsoft-onnxruntime-v1.23.2.tar.gz`, there is no error, but the folder name becomes `銇撱倱銇仭銇_ma莽茫`. So, `xjf` actually works, but the handling of Unicode paths is not perfect.

If you extract it using `cmake-3.31.10-windows-x86_64/bin/cmake.exe -E tar xjf microsoft-onnxruntime-v1.23.2.tar.gz`, you will encounter errors like:

```auto
CMake Error: Problem with archive_write_header(): Invalid empty pathname
CMake Error: Current file:
CMake Error: Problem extracting tar: microsoft-onnxruntime-v1.23.2.tar.gz

```

I still don’t know how to bypass this error in the CMake context.

`tar xf` works totally fine with `tar` from git:

```auto
tools\git-2.7.4-windows\usr\bin\tar xf microsoft-onnxruntime-v1.23.2.tar.gz

```

Maybe CMake should also update its own `tar`.

CMake uses `libarchive`. Are they these files? [Releases · microsoft/onnxruntime · GitHub](https://github.com/microsoft/onnxruntime/releases)
