Linkname can't be converted from UTF-8 to current locale, line 202

I get the error in the subject when I try to import a filesystem coming from an exported Docker container.

In detail, this is what I have done:

```sh
docker pull econcz/x86-alpine-glibc:ish-import
docker run -it econcz/x86-alpine-glibc:ish-import /bin/sh
cp /etc/apk/repositories /tmp/repositories
echo https://dl-cdn.alpinelinux.org/alpine/v3.12/main >>/etc/apk/repositories
echo https://dl-cdn.alpinelinux.org/alpine/v3.12/community >>/etc/apk/repositories
apk update
apk add ...
```
Then I have stopped the container and exported it with:

docker container export -o output.tar

Then I have copied `output.tar` into iPadOS. In iSH, I have chosen Settings (Gear) > Filesystems > Import, and I have selected the archive. Should I follow a different procedure?

Start by reproducing the filesystem import in iSH with the Docker-exported output.tar described in the report, focusing on the UTF-8-to-current-locale conversion error at line 202. Done means establishing whether this archive can be imported successfully or documenting the required export/import procedure.
