Dependency scanning when File::BOM is used in a via construct misses several
dependencies, resulting in errors when calling PAR packed executables. This
particularly applies to CJK locales.
The attached patch adds a preload section to include them. It could perhaps
also load Encode::HanExtra and Encode::JIS2K, but I have not done so in this
version.
The patch was tested using the code below. The file open is needed to trigger
the loading of the extra modules under "pp -x".
A more general solution might be to scan for "open .+?'<:via(\w+)'" constructs.
Regards,
Shawn.
use File::BOM;
open my $fh, '<:via(File::BOM)', $0 # just read ourselves
or die "Cannot open own code via File::BOM\n";
$fh->close;
