[bug-gnu-libiconv] RE: [rt.cpan.org #28850] Korean hanging CRITICAL

[Letellier, Aldo]

Ok found something looks like Text::Iconv hangs at unicode_loop_convert
() from /usr/local/lib/libiconv.so.2
I'm now using GNU libiconv 1.11
Let me try compiling libiconv with debug optimizer

Hello,

If you want to show a bug in GNU libiconv, you need to show a C or C++
program that exhibits a behaviour that does not comply with the manual
pages.

> > Iconv NOT OK

not.

This is well-known. On Solaris 10:

$ echo abc | /usr/bin/iconv -f EUC-KR -t ISO-2022-KR
Not supported EUC-KR to ISO-2022-KR
$ echo abc | /usr/bin/iconv -f EUC-KR -t UTF-8
abc
$ echo abc | /usr/bin/iconv -f UTF-8 -t ISO-2022-KR
abc

If you want to perform a conversion from EUC-KR to ISO-2022-KR, you
either need an iconv() implementation that supports it directly, such as
GNU libc iconv or GNU libiconv, or a utility code that converts via
UTF-8 if that is possible. For example you can use the 'striconveh'
module
from gnulib (it's under LGPL), see
   http://www.gnu.org/software/gnulib/MODULES.html#module%3Dstriconveh
