The current locale that +the program is running under is not supposed to be visible to Perl code +except within the scope of a S<C<use locale>>. However, until now under +certain circumstances, the character used for a decimal point (often a +comma) leaked outside the scope. + +This continues the work released in Perl v5.19.1. It turns out that +that did not catch all the leaks, including C<printf> and C<sprintf> not +respecting S<C<use locale>>. If your code is affected by this change, +simply add a S<C<use locale>>. + +Now, the only known place where C<'use locale'> is not respected is in +the stringification of L<$!|perlvar/$!>. =head1 Deprecations |
