Description

On my customer's site, it was due to the RSS widgets grabbing eBay feeds. But there are other calls to html_entity_decode() around.

Symptom:

Trying to decode HTML entities into UTF-8 results in the following error message:

Warning: cannot yet handle MBCS in html_entity_decode()!

The line is repeated about 200 times, then html_entity_decode just uses ISO-8859-1 charset.

The related php bugs:

Also occurs in BB:

Based on this thread, there is a potential fix:

Their implementation is in classes/core/String.inc.php, and goes like this:

function html2utf($str) {
	// convert named entities to numeric entities
	$str = strtr($str, String::getHTMLEntities());

	// use PCRE-aware replace function to replace numeric entities
	$str = String::regexp_replace('~&#x([0-9a-f]+);~ei', 'String::code2utf(hexdec("\\1"))', $str);
	$str = String::regexp_replace('~&#([0-9]+);~e', 'String::code2utf(\\1)', $str);

	return $str;
 }

Side note: best I'm aware, strtr is not mb safe, so the above code is potentially buggy in mb languages.
