path_tidy() doesn't work with non-UTF8 path

[shrektan]

The example illustrates the issue.

x <- "folder//fa\xE7ile.txt/"
Encoding(x) <- "latin1"
x
#> [1] "folder//façile.txt/"
fs::path_tidy(x)
#> Error in base::nchar(x, type, allowNA, keepNA): invalid multibyte string, element 1
fs::path_tidy(enc2utf8(x))
#> folder/façile.txt
