Code:
tr -dc '[:print:]'  < file > newfile

strips out any non-printable character in your current locale's charmap. newfile will have zero unprintable characters in it, in other words.

Is that what you want? See your man page for tr -- POSIX character classes may require double brackets -- e.g., '[[:print:]]' on your box

dumpcs(1)							   User Commands							 dumpcs(1)

NAME

       dumpcs - show codeset table for the current locale

SYNOPSIS

       dumpcs [-0123vw]

DESCRIPTION

       dumpcs  shows a list of printable characters for the user's current locale, along with their hexadecimal code values. The display device is
       assumed to be capable of displaying characters for a given locale. With no option, dumpcs displays the entire list of printable	characters
       for the current locale.

       With one or more numeric options specified, it shows EUC codeset(s) for the current locale according to the numbers specified, and in order
       of codeset number. Each non-printable character is represented by an asterisk "*" and enough ASCII space character(s) to  fill  that  code-
       set's column width.

OPTIONS

       -0	Show ASCII (or EUC primary) codeset.

       -1	Show EUC codeset 1, if used for the current locale.

       -2	Show EUC codeset 2, if used for the current locale.

       -3	Show EUC codeset 3, if used for the current locale.

       -v	"Verbose".  Normally,  ranges of non-printable characters are collapsed into a single line. This option produces one line for each
		non-printable character.

       -w	Replace code values with corresponding wide character values (process codes).

ENVIRONMENT VARIABLES

       The environment variables LC_CTYPE and LANG control the character classification throughout dumpcs. On entry to dumpcs,	these  environment
       variables  are  checked in that order. This implies that a new setting for LANG does not override the setting of LC_CTYPE. When none of the
       values is valid, the character classification defaults to the POSIX.1 "C" locale.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       |Availability		     |SUNWcsu			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       localedef(1), attributes(5)

NOTES

       dumpcs can only handle EUC locales.
