dumpcs
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.
