7

VERSION

9       version 0.007
10

SYNOPSIS

12        open my $fh, '<:utf8_strict', $filename;
13

DESCRIPTION

15       This module provides a fast and correct UTF-8 PerlIO layer. Unlike
16       perl's default ":utf8" layer it checks the input for correctness.
17

LAYER ARGUMENTS

19       allow_noncharacters
20       allow_surrogates
21

EXPORT

23       PerlIO::utf8_strict exports no subroutines or symbols, just a perl
24       layer "utf8_strict"
25

DIAGNOSTICS

27       Can't decode ill-formed UTF-8 octet sequence <%s>
28           (F) Encountered an ill-formed UTF-8 octet sequence. <%s> contains a
29           hexadecimal representation of the maximal subpart of the ill-formed
30           subsequence.
31
32       Can't interchange noncharacter code point U+%.4X
33           (F) Noncharacters is permanently reserved for internal use and that
34           should never be interchanged. Noncharacters consist of the values
35           U+nFFFE and U+nFFFF (where n is from 0 to 10^16) and the values
36           U+FDD0..U+FDEF.
