The problem here is that R thinks that your "Documents" directory has
a path that contains invalid UTF-8 bytes. This causes file.exists(...)
to fail when it tries to decode the path as UTF-8.

Can you at least temporarily disable OneDrive so that your Documents
directory would be "C:\\Users\\Alipio\\Documentos"? This should keep R
happy.

The proper solution would be to figure out why R is getting an
ANSI-encoded path to the Documents directory instead of it being in
UTF-8. I don't have Windows 11 installed or OneDrive set up to keep my
data, so you might need the help of someone else with this.

Sorry for the double e-mail.

It should also work if you set the environment variable R_USER to
some ASCII-representable path:

(in cmd.exe):

Please let me know if setting the environment variable helps.

I suspect that getenv() may be returning ANSI-encoded bytes even when
the UCRT locale encoding is set to UTF-8.
