hi!
I had problems with special chars in the pagetitle (in my case ""?") producing invalid HTML ... I modified wayfinder a little bit and it solved solve this problem. Maybe something similar should be standard for the next release?
I changed two lines (∼397) in Wayfinder.inc.php:
$tempDocInfo['linktext'] = $tempDocInfo[$useTextField];
$tempDocInfo['title'] = $tempDocInfo[$this->_config['titleOfLinks']];
changed to
$tempDocInfo['linktext'] = htmlspecialchars(html_entity_decode($tempDocInfo[$useTextField]));
$tempDocInfo['title'] = htmlspecialchars(html_entity_decode($tempDocInfo[$this->_config['titleOfLinks']]));
I just couldn´t find the correct place t do the same with the description ...
Used: MODx 0.9.6 RC1, Wayfinder 2.0
