DESCRIPTION¶
This class represents a literal character, no matter how specified.
METHODS¶
This class provides the following public methods. Methods not documented here
are private, and unsupported in the sense that the author reserves the right
to change or remove them without notice.
ordinal¶
print 'The ordinal of ', $token->content(),
' is ', $token->ordinal(), "\n";
This method returns the ordinal of the literal if it can figure it out. It is
analogous to the "ord" built-in.
It will not attempt to determine the ordinal of a unicode name
("\N{...}") unless charnames has been loaded, and supports the
vianame() function. Instead, it will return "undef". Users of
Perl 5.6.2 and older may be out of luck here.
Unicode code points (e.g. "\N{U+abcd}") should work independently of
charnames, and just return the value of "abcd".
It will never attempt to return the ordinal of an octet ("\C{...}")
because I don't understand the syntax.

Support is by the author. Please file bug reports at <
