Is this GNU grep? The GNU utilities, unusually, try to handle your character set as appropriate. This means when you tell it to be case insensitive, that busts out some pretty heavy-duty routines in order to do so properly.

wcsncasecmp
WCSNCASECMP(3) Linux Programmer's Manual WCSNCASECMP(3)
NAME
wcsncasecmp - compare two fixed-size wide-character strings, ignoring case
SYNOPSIS
#include <wchar.h>
int wcsncasecmp(const wchar_t *s1, const wchar_t *s2, size_t n);
DESCRIPTION
The wcsncasecmp function is the wide-character equivalent of the strncasecmp function. It compares the wide-character string pointed to by
s1 and the wide-character string pointed to by s2, but at most n wide characters from each string, ignoring case differences (towupper,
towlower).
RETURN VALUE
The wcsncasecmp function returns zero if the wide-character strings at s1 and s2, truncated to at most length n, are equal except for case
distinctions. It returns a positive integer if truncated s1 is greater than truncated s2, ignoring case. It returns a negative integer if
truncated s1 is smaller than truncated s2, ignoring case.
CONFORMING TO
This function is a GNU extension.
SEE ALSO
strncasecmp(3), wcsncmp(3)
NOTES
The behaviour of wcsncasecmp depends on the LC_CTYPE category of the current locale.
