I'm not familiar with perl's unicode capabilities, but assuming that the unicode 2026 character is encoded in utf8, a non-unicode/utf-8 aware approach will have to match a sequence of three bytes: 0xE2 0x80 0xA6.
HI
Hi I have a character string which contains some special characters and I need it to display as a hex string.
For example, the sample i/p string: ×¥ïA Å gïÛý and
the o/p should be : D7A5EF4100C5010067EFDBFD
Any pointers or sample code pls. (5 Replies)

idna_to_unicode_44i
idna_to_unicode_44i(3) libidn idna_to_unicode_44i(3)NAME
idna_to_unicode_44i - API function
SYNOPSIS
#include <idna.h>
int idna_to_unicode_44i(const uint32_t * in, size_t inlen, uint32_t * out, size_t * outlen, int flags);
ARGUMENTS
const uint32_t * in
input array with unicode code points.
size_t inlen
length of input array with unicode code points.
uint32_t * out
output array with unicode code points.
size_t * outlen
on input, maximum size of output array with unicode code points, on exit, actual size of output array with unicode code points.
int flags an Idna_flags value, e.g., IDNA_ALLOW_UNASSIGNED or IDNA_USE_STD3_ASCII_RULES.
DESCRIPTION
The ToUnicode operation takes a sequence of Unicode code points that make up one domain label and returns a sequence of Unicode code
points. If the input sequence is a label in ACE form, then the result is an equivalent internationalized label that is not in ACE form,
otherwise the original sequence is returned unaltered.
ToUnicode never fails. If any step fails, then the original input sequence is returned immediately in that step.
The Punycode decoder can never output more code points than it inputs, but Nameprep can, and therefore ToUnicode can. Note that the number
of octets needed to represent a sequence of code points depends on the particular character encoding used.
The inputs to ToUnicode are a sequence of code points, the AllowUnassigned flag, and the UseSTD3ASCIIRules flag. The output of ToUnicode is
always a sequence of Unicode code points.
RETURN VALUE
Returns Idna_rc error condition, but it must only be used for debugging purposes. The output buffer is always guaranteed to contain the
correct data according to the specification (sans malloc induced errors). NB! This means that you normally ignore the return code from
this function, as checking it means breaking the standard.
