No. It will remove characters that are not in the "ASCII range" from 0x00 up to 0x7F. ASCII control chars (non- printable, incl. white space) will NOT be removed. It will remove characters above ASCII, starting with 0x80 (= 128), including "extended ASCII" or any other character set / encoding like UTF-8, on which your locale setting may depend.


You may want to consider starting over, making up your mind which chars you need, and which you don't, and rephrase your specification. Do you have examples of "target" chars ?

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. SunOS 5.11 20 Dec 1996 dumpcs(1)
