In principle not too difficult:
, but you should be aware that these character graphics chars usually belong to a multibyte character set like utf-8 or so which may impose restrictions.

Hello,
Is there a simpler way to remove special characters (color codes) from each lines in a log file?
I use sed like in the example below but I think there should be a more simple way to achieve the same result:
$ cat -vet file1

Maybe to convert the file somehow?

mblen
MBLEN(3) Linux Programmer's Manual MBLEN(3)NAME
mblen - determine number of bytes in next multibyte character
SYNOPSIS
#include <stdlib.h>
int mblen(const char *s, size_t n);
DESCRIPTION
If s is not a NULL pointer, the mblen function inspects at most n bytes of the multibyte string starting at s and extracts the next com-
plete multibyte character. It uses a static anonymous shift state only known to the mblen function. If the multibyte character is not the
null wide character, it returns the number of bytes that were consumed from s. If the multibyte character is the null wide character, it
returns 0.
If the n bytes starting at s do not contain a complete multibyte character, mblen returns -1. This can happen even if n >= MB_CUR_MAX, if
the multibyte string contains redundant shift sequences.
If the multibyte string starting at s contains an invalid multibyte sequence before the next complete character, mblen also returns -1.
If s is a NULL pointer, the mblen function resets the shift state, only known to this function, to the initial state, and returns non-zero
if the encoding has non-trivial shift state, or zero if the encoding is stateless.
RETURN VALUE
The mblen function returns the number of bytes parsed from the multibyte sequence starting at s, if a non-null wide character was recog-
nized. It returns 0, if a null wide character was recognized. It returns -1, if an invalid multibyte sequence was encountered or if it
couldn't parse a complete multibyte character.
CONFORMING TO
ISO/ANSI C, UNIX98
SEE ALSO mbrlen(3)NOTES
The behaviour of mblen depends on the LC_CTYPE category of the current locale.
The function mbrlen provides a better interface to the same functionality.
