How do I get rid of strange characters

I have inside a text file several words with strange characters (ex: HE^@^@^@^@^@^@^@^@^@^@^@^@LLO).If I try to print the text file everything that's on the right of those strange chars on the line is not printed. If I want to get the word HELLO, AWK returns it "HELLO", but with length = 17 chars. I tried also to get the char's ASCII code but it doesn't seem to have one!

Not quite sure what you are asking but if you just want to physically remove the rubbish and leave the word HELLO in the file then you can pass the command s/HE.*LLO/HELLO/ in vi or if you need to do it from the command line or in a shell script, try:-
cat rubish_file ¦ sed 's/HE.*LLO/HELLO/g' > hello_file

Hope that helps.
