The binary strings that could be accessed correspond to the customization
variables strings or arrays INCLUDE_DIRECTORIES, CSS_FILES,
MACRO_EXPAND and INTERNAL_LINKS. If they need to be decoded into
character strings, for example to appear in error messages, it is possible to
use the COMMAND_LINE_ENCODING customization variable value as
encoding name to mimic how the decoding of these strings from the command line
is done in the main program and in the converters. For example:
my $macro_expand_fname = $self->get_conf('MACRO_EXPAND');
my $encoding = $self->get_conf('COMMAND_LINE_ENCODING');
if (defined($encoding)) {
$macro_expand_fname = Encode::decode($encoding, $macro_expand_fname);
}
