For documents we are indexing via the PHP client, we are currently
using the following regex to strip control characters from each field
that might contain them:
function apachesolr_strip_ctl_chars($text) {
// See: http://w3.org/International/questions/qa-forms-utf-8.html
// Printable utf-8 does not include any of these chars below x7F
return preg_replace('@[\x00-\x08\x0B\x0C\x0E-\x1F]@', ' ', $text);
}
