The default is “appkitâ€. Currently it must be between 1 and 6 characters and the characters can only be A-Z, a-z, 0-9. =head2 char_count() Lazy wrapper of L<String::UnicodeUTF8>’s char_count(). =head2 bytes_size() Lazy wrapper of L<String::UnicodeUTF8>’s bytes_size(). =head2 prefix() Get/Set the prefix attribute. =head2 portable_crlf() Returns a portable CRLF. (i.e. \r\n is not portable) =head2 zero_but_true() Returns a zero-but-true string. =head1 DIAGNOSTICS Setting the prefix to an invalid value can result in an error that is descriptive of the problem. =head1 CONFIGURATION AND ENVIRONMENT Requires no configuration files or environment variables. =head1 DEPENDENCIES L<String::UnicodeUTF8> =head1 INCOMPATIBILITIES None reported. =head1 BUGS AND LIMITATIONS No bugs have been reported.
