devtools::release() breaks with unicode characters in tempdir() path

[mikolajsp]

Hello,

I've encountered an issue with the devtools::submit_cran() function. I would like to mention at the beginning, that I'm not sure if the problem is in the devtools package, or in some dependency like httr.

I'm working in a Windows environment, and my username has a unicode character in it, specifically "ł". For this reason, the default Windows temporary directory

Replication of the issue:

1. Set the system environment variable TMPDIR to a path containing the character "ł", in my case it is C:\Users\Mikołaj\AppData\Local\Temp

2. Try to release something to CRAN

Workaround:

Set the TMPDIR to a path without Unicode characters e.g. C:\temp

Possibly a duplicate of #2422

I would need to see more specifics to know for sure (a reprex, including session info), but I suspect the root problem might be one of the known issues in fs, such as r-lib/fs#383.
