>Description:
This is a summary of a discussion on pkgsrc-users@
http://mail-index.netbsd.org/pkgsrc-users/2007/05/12/0002.html

1. nl_langinfo (CODESET) returns "646" which is a synonym of "ASCII".
2. libiconv is not available on OpenBSD by default (only in ports).
3. pkgsrc's libiconv doesn't support codeset "646".

As a result, some packages fail to compile on OpenBSD 4.1. For exampe, gtk2 
cannot be build.

>How-To-Repeat:
I reproduced it firt time when I tried to build gtk2. Or simply execute
$ echo "hello" | /usr/pkg/bin/iconv -f UTF-8 -t 646

Currently, it displays

$ echo "hello" | /usr/pkg/bin/iconv -f UTF-8 -t 646
/usr/pkg/bin/iconv: conversion to 646 unsupported
/usr/pkg/bin/iconv: try '/usr/pkg/bin/iconv -l' to get the list of supported 
encodings

>Fix:
Modify libiconv to support codeset "646"?
