Thanks for the info. If the problem demonstrated by your snippet there is the one that is causing Text::CSV to fail on the real data of interest, then it would seem that you have to impose "proper handling" of the BOM yourself. Delete it from the input before passing the data to Text::CSV.

Since U+FEFF is (a) unlikely to be present anywhere else besides the beginning of the input file and (b) interpreted as a "zero width non-breaking space" if it were to be found anywhere else in the file (i.e., it lacks any linguistic semantics whatsoever), it should suffice to just delete it - here's a version of your snippet that doesn't produce an error:

use Encode qw( decode_utf8 ); use Text::CSV_XS; my $csv_bytes = qq/\x{feff}"Field One","Field 2",3,4,"Field 5"\r\n/; my $csv_record = decode_utf8($csv_bytes); $csv_record =~ tr/\x{feff}//d; ## Add this, and there's no error. my $csv = Text::CSV_XS->new( { auto_diag => 1 } ); $csv->parse($csv_record);
I suppose it's kind of sad that you need to do that for Text::CSV to work, but at least it works.
