=head1 VERSION
version 0.006
=head1 SYNOPSIS
open my $fh, '<:utf8_strict', $filename;
=head1 DESCRIPTION
This module provides a fast and correct UTF-8 PerlIO layer. Unlike perl's default C<:utf8> layer it checks the input for correctness.
=head1 LAYER ARGUMENTS
=over 4
=item allow_noncharacters
=item allow_surrogates
=back
=head1 EXPORT
PerlIO::utf8_strict exports no subroutines or symbols, just a perl layer C<utf8_strict>
=head1 DIAGNOSTICS
=over 4
=item Can't decode ill-formed UTF-8 octet sequence <%s>
(F) Encountered an ill-formed UTF-8 octet sequence. <%s> contains a hexadecimal
representation of the maximal subpart of the ill-formed subsequence.
=item Can't interchange noncharacter code point U+%.4X
(F) Noncharacters is permanently reserved for internal use and that should
never be interchanged. Noncharacters consist of the values U+nFFFE and U+nFFFF
(where n is from 0 to 10^16) and the values U+FDD0..U+FDEF.
