Now, this is completely different from what you posted in #1. And, still not clear.
There's only one pattern occurrence in above sample, with value 00. That should become 01, understood. you don't say anything about the next pattern occurrence. Should that become 02 regardless of its initial value? Or, its initial value + 1? And, you didn't answer the question about the 0x7F value, should that ever occur.

mbrune
MBRUNE(3) BSD Library Functions Manual MBRUNE(3)
NAME
mbrune, mbrrune, mbmb -- multibyte rune support for C
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <rune.h>
char *
mbrune(const char *string, rune_t rune);
char *
mbrrune(const char *string, rune_t rune);
char *
mbmb(const char *string, char *pattern);
DESCRIPTION
The 4.4BSD ``rune'' functions have been deprecated in favour of the ISO C99 extended multibyte and wide character facilities and should not
be used in new applications. Consider working with wide characters instead, and using wcschr(3), wcsrchr(3), and wcsstr(3) instead of these
functions.
These routines provide the corresponding functionality of strchr(), strrchr() and strstr() for multibyte strings.
The mbrune() function locates the first occurrence of rune() in the string pointed to by string. The terminating NUL character is considered
part of the string. If rune is '
