Summary: POPfetcher Charset Conversion Badly Broken

Initial Comment:
Tested with Serendipity 1.4.1, downloaded newest POPfetcher Plugin with Spartacus.

Problem: Character Conversion of e-mails is not implemented correctly. Only works with latin1 <-> utf-8.
the php Functions utf8_en/decode($string) are used, which only de/encodes latin1 to/from utf8.

Instead, depending on avaible php extension, the following should be used:

in PHP6:
function decode($string, $charset) {
            return unicode_decode($string,$charset);
}

in PHP4/5 with iconv compiled in:
function decode($string, $charset) {
            $destcc=LANG_CHARSET;
            if (!empty($destcc)) $destcc="utf-8";
            return iconv($charset,$destcc,$string);   
}

in PHP4/5 with recodelib extension enabled:
function decode($string, $charset) {
            $destcc=LANG_CHARSET;
            if (!empty($destcc)) $destcc="utf-8";
            return recode_string("$charset..$destcc",$string);
}

utf8_en/decode can _only_ be used if latin1<->utf-8 conversion is needed. Otherwise an error should be thrown.

Message:
Hi!

Can you give a description of your setup where you faced the bug? Which
charset did you configure for serendipity, and in which charset was your
mail?

The mimeDecode library also translates the charsets, AFAIK - so what I
have in mind was that it takes care of always either supplying latin1 or
UTF-8 content. If that's not the case, I'd like to setup an installation
that matches your to investigate the issue properly.

Thanks,
Garvin
