Re: The module version works, but the standlone version crashes with "Malformed UTF-8 character"

"D" corresponds to "i + o" whose documentation in perlrun states (emphasis mine):

> The "io" options mean that any subsequent open() (or similar I/O operations) in the current file scope will have the ":utf8" PerlIO layer implicitly applied to them, in other words, UTF-8 is expected from any input stream, and UTF-8 is produced to any output stream.

If you put the call to open into a module, it falls out of the current file scope.

The -C is intended for oneliners, in larger programs and modules, use binmode, explicit layers with 3-arg open, or open.pm.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

You are right my friend. I must have overseen it. If I start with "perl -CS" instead of "perl -CDS" it works in both versions. I thank you very much.	[reply]
