The directory is temporary, as it says in the name. pip will destroy it when it finishes running if it failed or succeeded.

Your error is pretty clear, it's telling you that while reading the readme file it found a unicode character it doesn't know how to decode.

This looks like it's a known issue, https://github.com/aboSamoor/polyglot/issues/127, https://github.com/aboSamoor/polyglot/issues/93, https://github.com/aboSamoor/polyglot/issues/91. A variety of solutions are provided in the linked issues.
