SAS_READ Unsupported character set code: 204 encoding set to 'any'

[sclewis23]

I'm facing issues reading SAS files when the encoding is set to 'any'.
Error is Unsupported character set code: 204.
See reprex including simple SAS code to create sample file.

#SAS CODE:
# Data Weight2; 
# input IDnumber $ week1 week16; 
# AverageLoss=week1-week16; 
# datalines; 
# 2477 195 163
# 2431 220 198
# 2456 173 155
# 2412 135 116
# ;
# libname outlib '~' outencoding='UTF-8';
# data outlib.Weight_utf8;
# Set Weight2;
# Run;
# libname out_any '~' outencoding='any';
# data out_any.Weight2;
# Set Weight2;
# Run;
library(haven);
read_sas("~/weight2.sas7bdat");
#> Unsupported character set code: 204
#> Error in df_parse_sas_file(spec_data, spec_cat, encoding = encoding, catalog_encoding = catalog_encoding, : Failed to parse /home/[email protected]/weight2.sas7bdat: File has an unsupported character set.

@hadley - It looks like WizardMac/ReadStat has added support for "any" encoding....How often do you incorporate changes from ReadStat ?
