I would like to remove all the special characters from a file and replace it with the closest character possible.

Is there a script that I could use to do this?

what characters do you consider special?
and what characters do you consider closest?

Any characters that unix can not interpt.

I.e. Dec value 128 to 225
     Hex value 80 to FF
     (both of the above are the same range).

Would it be possible to have a script which would ask me to enter in a letter of my choice to be a replacement (for the special character)?

Right, but I need a perl script that will work on win32 platforms.  When I transfer the files from windows to unix the special characters are lost.  Thus having no special characters in unix.

I ftp (ascii). But when I open them up in Solaris 2.6 they are replaced with either nothing or some other weird character.
