TYPO3 Core

When using the crawler extension, converting the charset of the indexed externel URL to UTF-8 fails if the external page does not give the charset in the metatags and is "iso-8859-1".

I solved the problem by adding one line the the function convertHTMLToUtf8 (in the file "class.indexer.php"):

// Find charset:
        $charset = $charset ? $charset : $this->getHTMLcharset($content);
        $charset = $this->csObj->parse_charset($charset);

// make the indexer convert the page if no charset is given...
        if (!$charset) $charset='iso-8859-1';

Of course, this assumes, that the pages is in iso-8859-1 if no charset is given. But this is more likely true than assuming that the page is in utf-8 (as it works now).
