Describe your issue

Unfortunately, libarchive doesn't seem to be very good at handling UTF8 encoded paths in packages (.tar.bz2 files). I created a test-case in rattler-build to create a package with weird file names (utf8, long files, etc.). Unfortunately micromamba fails at extracting the files correctly. Specifically a file with File(Glob …).tmSnippet doesn't work since the ellipsis is UTF8 encoded.

We might want to consider to use our implementation to create the files instead of relying on the archive_writer.

I also tested tar.exe (pre-installed on Windows) and it has the same UTF problem when extracting the .tar.bz2 file.
