Well, you are close, but you wrong gen_id's.. generator 1 is the rules, and 
no preprocessor generated alerts will match.


[snort] (portscan) Open Port   unclassified
[snort] (portscan) UDP Portsweep   unclassified

sfportscan is generator 122 so you need to suppress gen_id 122 with sig_id 
27 and 19.

[snort] (http_inspect) BARE BYTE UNICODE ENCODING

http_inspect is generator 119 so you need to suppress gen_id 119 sig_id 4

Try these instead:

suppress gen_id 122, sig_id 27:
suppress gen_id 122, sig_id 19:
suppress gen_id 119, sig_id 4:
