25 | XXX New core language features go here. Summarise user-visible core language |
26 | enhancements. Particularly prominent performance optimisations could go | |

31 | =head2 Improved ability to mix locales and Unicode, including UTF-8 locales |
32 | ||
33 | An optional parameter has been added to C<use locale> | |
34 | ||
35 | use locale ':not_characters'; | |
36 | ||
37 | which tells Perl to use all but the C<LC_CTYPE> and C<LC_COLLATE> | |
38 | portions of the current locale. Instead, the character set is assumed | |
39 | to be Unicode. This allows locales and Unicode to be seamlessly mixed, | |
40 | including the increasingly frequent UTF-8 locales. When using this | |
41 | hybrid form of locales, the C<:locale> layer to the L<open> pragma can | |
42 | be used to interface with the file system, and there are CPAN modules | |
43 | available for ARGV and environment variable conversions. | |

52deee2e DR |
385 | recently posted to the comp.lang.perl.misc newsgroup and the perl |
386 | bug database at http://rt.perl.org/perlbug/ . There may also be | |
44691e6f AB |
387 | information at http://www.perl.org/ , the Perl Home Page. |
388 | ||
389 | If you believe you have an unreported bug, please run the L<perlbug> | |
52deee2e DR |
390 | program included with your release. Be sure to trim your bug down |
391 | to a tiny but sufficient test case. Your bug report, along with the | |
392 | output of C<perl -V>, will be sent off to perlbug@perl.org to be | |
393 | analysed by the Perl porting team. | |
44691e6f AB |
394 | |
395 | If the bug you are reporting has security implications, which make it | |
52deee2e DR |
396 | inappropriate to send to a publicly archived mailing list, then please send |
397 | it to perl5-security-report@perl.org. This points to a closed subscription | |
398 | unarchived mailing list, which includes | |
399 | all the core committers, who will be able | |
400 | to help assess the impact of issues, figure out a resolution, and help | |
401 | co-ordinate the release of patches to mitigate or fix the problem across all | |
402 | platforms on which Perl is supported. Please only use this address for | |
403 | security issues in the Perl core, not for modules independently | |
404 | distributed on CPAN. | |
