I need to replace some non text characters in some automatically generated files with spaces.
Although they are text files after processing some characters are added and the cannot be edited as text any more

Is there a sed command to do that?

    Depending on your platform and sed version, you may or may not be able to do something like s/[\000-\037]/ /g; but the portable and simple alternative is this:

    tr '\000-\037' ' ' <input >output

    (All character codes are “binary”; I have assumed you mean control characters, but if you mean 8-bit characters \200-\377 or something else altogether, it’s obviously trivial to adjust the range.)
