The archive contains a file 'bokm\0345l.alias' which uses an invalid utf-8 encoding of the letter 'å'. UTF-8 doesn't allow single byte encoding above 0x7F, but this file has 0xE5, which needs to be escaped. Creating a file with 'å' manually results in bash encoding the name correctly with escaping 0xc3 0xa5: "bokm\303\245l.alias" vs "bokm\345l.alias" This issue has only been observed on systems with rootfs on ZFS, but any random tool that would use the file could fail on other systems. ZFS validates the encoding when files are created and it fails file creation. My pool has utf8only=yes normalization=formD, it it matters. Reproducible: Always Steps to Reproduce: 1.

Well, I am not sure, what I can do here, as even the unpacking process fails for you. If that would work, we could do some prepare and rename the stuff. Seems to be ZFS specific, as it works fine for me.
I asked upstream, if they could update the package. This is likly a ZFS specific problem with 'utf8only=yes', I don't see really a bug fix, since IMHO it still should be able to unpack.
If I unpack to /tmp (tmpfs) it works, but a ls in bash shows the file as having bad encoding by printing escapes and not the 'å'. So bash isn't happy either.
You can see this illegal use has been reported elsewhere https://issues.guix.gnu.org/36087
Testing on vfat with utf8 option it gives the same result as ZFS when unpacking. I guess the only way to fix this is upstream?
