I don't see the last character :( why?
http://www.unicode.org/cgi-bin/...t=%F0%A0%B2%8E
it's this character you see it because this character is specific to Shanghainese, and has been added only recently (some years ago, maybe less) to the unicode norm, so for this two reasons 99,99% fonts are not able to render it
on my twitter i've once give a link to a open source font able to render shanghainese characters
takk takk :)
