1. Can’t reproduce it and it got never reported. Will be come from an plugin, a wrong loaded jquery version in relation to the jquery ui and/or the datepicker. Or maybe a javascript error, but then it shouldn’t come up.
2. The invoice supports all signs that are available in latin as well as in unicode. You can try to add your sign in /lib/modules/invoice/html2pdf/_tcpdf/unicode_data.php. Unfortunately there is no better way from html to pdf.
