Ok I hope i can help .. i have attached a zip contianing a new version of reportico_report_tcpdf.php with a modification in it which may help....
If you look at line 2483 you will see a function format_column with the following lines .. i have added here at the end two lines one to a function that should convert html &xxx; stirngs to normal characters notation and another that should replace the ' to a quote. This is the place where you can experiment but give this a go first..
function format_column(& $column_item) // PDF
//if ( $this->line_count < 3 ) $this->debugFile("==========> FC $this->draw_mode $h = $this->required_line_height");
if ( !$this->show_column_header($column_item) )
// Keep track of how many columns in current row to print if calculating
// or already printed if drawing so we can calculate when to draw
// borders around a cell
if ( $this->draw_mode == "CALCULATE" )
$k =& $column_item->column_value;
/* These are added lines ************************ */
$k = htmlspecialchars_decode($k);
$k = preg_replace("/'/", "'", $k);
