how to grep junk characters in a file
hi guys,

I am generating a file from datastage (an etl tool).

Now the file is having some junk characters like ( Á,L´±,ñ and so on)..

I want to use the grep function to figure out all the junk characters and their location.

Can somebody help me out in finding it out.. if possible i just want to replace each of them with a ""(empty string).

Thanks for your help in advance..
