\*(C'\fR tag so that markdown characters won't be processed. Regions of \f(CW\*(C`:markdown\*(C'\fR or \f(CW\*(C`:html\*(C'\fR will be processed as \s-1POD\s0 and included.

If you want Pod::Markdown to return encoded octets, there are two attributes to assist: \*(L"match_encoding\*(R" and \*(L"output_encoding\*(R". .PP When an output encoding is requested any characters that are not valid for that encoding will be escaped as \s-1HTML\s0 entities. .PP This is not 100% safe, however. .PP Markdown escapes all ampersands inside of code spans, so escaping a character as an \s-1HTML\s0 entity inside of a code span will not be correct. However, with pod's \f(CW\*(C`S\*(C'\fR and \f(CW\*(C`E\*(C'\fR sequences it is possible to end up with high-bit characters inside of code spans. .PP So, while \f(CW\*(C`output_encoding => \*(Aqascii\*(Aq\*(C'\fR can work, it is not recommended. For these reasons (and more), \f(CW\*(C`UTF\-8\*(C'\fR is the default, fallback encoding (when one is required). .PP If you prefer \s-1HTML\s0 entities over literal characters you can use \&\*(L"html_encode_chars\*(R" which will only operate outside of code spans (where it is safe). .SH "METHODS" .IX Header "METHODS" .SS "new" .IX Subsection "new" .Vb 1 \& Pod::Markdown\->new(%options); .Ve .PP The constructor accepts the following named arguments: .IP "\(bu" 4 \&\f(CW\*(C`local_module_url_prefix\*(C'\fR .Sp Alters the perldoc urls that are created from \f(CW\*(C`L<>\*(C'\fR codes when the module is a \*(L"local\*(R" module (\f(CW"Local::*"\fR or \f(CW"Foo_Corp::*"\fR (see perlmodlib)). .Sp The default is to use \f(CW\*(C`perldoc_url_prefix\*(C'\fR. .IP "\(bu" 4 \&\f(CW\*(C`local_module_re\*(C'\fR .Sp Alternate regular expression for determining \*(L"local\*(R" modules.

It is not recommended to turn this off with an empty local_module_url_prefix, as the resulting local module URLs can be confused with IPv6 addresses by web browsers. .SS "html_encode_chars" .IX Subsection "html_encode_chars" A string of characters to encode as html entities (using \*(L"encode_entities\*(R" in HTML::Entities if available, falling back to numeric entities if not). .PP Possible values: .IP "\(bu" 4 A value of \f(CW1\fR will use the default set of characters from HTML::Entities (control chars, high-bit chars, and \f(CW\*(C`<&>"\*(Aq\*(C'\fR). .IP "\(bu" 4 A false value will disable. .IP "\(bu" 4 Any other value is used as a string of characters (like a regular expression character class). .PP By default this is disabled and literal characters will be in the output stream. If you specify a desired \*(L"output_encoding\*(R" any characters not valid for that encoding will be \s-1HTML\s0 entity encoded. .PP \&\fBNote\fR that Markdown requires ampersands (\f(CW\*(C`&\*(C'\fR) and left angle brackets (\f(CW\*(C`<\*(C'\fR) to be entity-encoded if they could otherwise be interpreted as html entities. If this attribute is configured to encode those characters, they will always be encoded.
