[R-pkg-devel] Windows R 4.2.0 package will not load with UTF-8 encoding

Thank you for the check of the CRAN builds.  I also checked that as a first
step.  Perhaps there is some difference between the CRAN setups, as I have
reproduced this on 3 Windows 10 machines with clean installs of R 4.2.0,
and it has been reported by other users.  I also noted in the post that
building and installing via devtools reports success (  ** testing if
installed package can be loaded from temporary location ), however, a
subsequent attempt to load hangs.

Apologies for the pages of minutia.  I endeavored to post reproduceable
example. I'm unable to show the failure since it simply hangs at the prompt
with CPU spinning and memory cyclically ramping and declining.  One has to
kill R. The posted commands show the workaround, not the failure.

I since found that just changing the LC_COLLATE is enough to allow the
library to load :

Sys.setlocale('LC_COLLATE','English')

[1] "English_United States.1252"

Sys.getlocale()

[1] "LC_COLLATE=English_United States.1252;LC_CTYPE=English_United
States.utf8;LC_MONETARY=English_United
States.utf8;LC_NUMERIC=C;LC_TIME=English_United States.utf8"

Again, apologies for my naivety.

Dear R package developers,

Starting with R 4.2.0 package rEDM (

https://cran.r-project.org/package=rEDM)

will not load [library( rEDM )] on Windows with the default UTF-8

encoding.

When the locale is changed from UTF-8 to non UTF-8, the package loads

and

runs. One can also change the locale to non-UTF-8, load the package,

detach

and unload the package, change the locale back to UTF-8, then load and

run

without issue.

Note that installation from source reports:
     ** testing if installed package can be loaded from temporary

location

and completes (record below).

This package uses Rcpp to wrap a C++ API.

Having searched here and in general, I don't find that others

experiencing

this issue.

I have tried
    Ensure all source files are UTF-8 encoded
    Removed non-ASCII characters from all source files
    Specify non-ASCII characters with \uXXXX
    Checked vignette encoding
    Added "Encoding : UTF-8" to DESCRIPTION

Please excuse my encoding and Windows naivety.

Here is a demonstration changing the encoding to load the package, along
with unloading & reloading under UTF-8:

### All package tests pass....

detach( 'package:rEDM', unload = TRUE )

Simplex( dataFrame = Lorenz5D, columns = 'V1', target = 'V2', lib = "1

500", pred = "501 505", E = 5 )
Error in Simplex(dataFrame = Lorenz5D, columns = "V1", target = "V2",  :
    could not find function "Simplex"

I don't see any attempt to load the package.  You attempted to use the
function Simplex and it was not found.  That indicates the package is
not loaded, but not why.

What you should show are the messages you get when you start a clean
copy of R and immediately attempt to load the package using library().
It's helpful that you posted sessionInfo(); I'd include that again with
the new information, in case anything is different.
