Description
Description
The following code:
<?php
var_dump(grapheme_extract('', 42));
var_dump(grapheme_extract('ab', 42, offset: 2));
Resulted in this output:
bool(false)
bool(false)
But I expected this output instead:
string(0) ""
string(0) ""
Per documentation, the offset ought to be less then or equal to the length of the string (which I consider an appropriate range).

Research direction
Start by reproducing the two grapheme_extract() calls from the report, then locate the function's implementation and related tests in php-src. Verify that an offset equal to the haystack length returns an empty string for both cases, while behavior for other offsets remains unchanged.
