NAME

Unicode::UTF8 - Encoding and decoding of UTF-8 encoding form.

SYNOPSIS

use Unicode::UTF8 qw[decode_utf8 encode_utf8];

$string = decode_utf8($octets);
$octets = encode_utf8($string);

DESCRIPTION

This module provides functions to encode and decode UTF-8 encoding form as defined by Unicode and ISO/IEC 10646:2011.

FUNCTIONS

decode_utf8($octets)

Returns an decoded representation of $octets in UTF-8 encoding as a character string.

Issues a warning if $octets contains an ill-formed UTF-8 sequence or an encoded code point which can't be interchanged.

encode_utf8($string)

Returns an encoded representation of $string in UTF-8 encoding as an octet string.

Issues a warning if $string contains a code point which can't be interchanged or represented in UTF-8 encoding form.

EXPORTS

None by default. All functions can be exported using the :all tag or individually.

DIAGNOSTICS

Can't decode a wide character string

(F) Wide character in octets.

Can't decode ill-formed UTF-X octet sequence <%s> in position %u

(F) Encountered an ill-formed octet sequence in Perl's internal representation of wide characters.

Can't decode ill-formed UTF-8 octet sequence <%s> in position %u

(W utf8) Encountered an ill-formed UTF-8 octet sequence. <%s> contains a hexadecimal representation of the maximal subpart of the ill-formed subsequence.

Can't interchange noncharacter code point U+%.4X

(W utf8) 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.

Can't represent surrogate code point U+%.4X in UTF-8 encoding form

(W utf8) Surrogate code points are designated only for surrogate code units in the UTF-16 character encoding form. Surrogates consist of code points in the range U+D800 to U+DFFF.

Can't represent super code point \x{%X} in UTF-8 encoding form

(W utf8) Code points greater than U+10FFFF. Perl's extended codespace.
