I'm not sure I need to show internal code that has nothing to do with it. Basically I think the issue comes from the maximum number of items into a byte array. Say an example program already contains this code:
That would mean that the maximum number of elements is the maximum value an integer can achieve, which in Java is 2147483647, so make that bytes. That implies the maximum length of piece to extract can be up to 2 GB approximately. What happens if I want to extract a piece of about 7 GB? Even in the 2GB case, I have no idea if the content is stored into ram memory, which will cause problems on low specs computers.

grapheme_extract
GRAPHEME_EXTRACT(3) 1 GRAPHEME_EXTRACT(3)grapheme_extract - Function to extract a sequence of default grapheme clusters from a text buffer, which must be encoded in UTF-8.
Procedural style
SYNOPSIS
string grapheme_extract (string $haystack, int $size, [int $extract_type], [int $start], [int &$next])
DESCRIPTION
Function to extract a sequence of default grapheme clusters from a text buffer, which must be encoded in UTF-8.
PARAMETERS
o $haystack
- String to search.
o $size
- Maximum number items - based on the $extract_type - to return.
o $extract_type
- Defines the type of units referred to by the $size parameter:
oGRAPHEME_EXTR_COUNT (default) - $size is the number of default grapheme clusters to extract.
oGRAPHEME_EXTR_MAXBYTES - $size is the maximum number of bytes returned.
oGRAPHEME_EXTR_MAXCHARS - $size is the maximum number of UTF-8 characters returned.
o $start
- Starting position in $haystack in bytes - if given, it must be zero or a positive value that is less than or equal to the length
of $haystack in bytes. If $start does not point to the first byte of a UTF-8 character, the start position is moved to the next
character boundary.
o $next
- Reference to a value that will be set to the next starting position. When the call returns, this may point to the first byte
position past the end of the string.
RETURN VALUES
A string starting at offset $start and ending on a default grapheme cluster boundary that conforms to the $size and $extract_type speci-
fied.
EXAMPLES
Example #1
grapheme_extract(3) example
<?php
$char_a_ring_nfd = "axCCx8A"; // 'LATIN SMALL LETTER A WITH RING ABOVE' (U+00E5) normalization form "D"
$char_o_diaeresis_nfd = "oxCCx88"; // 'LATIN SMALL LETTER O WITH DIAERESIS' (U+00F6) normalization form "D"
print urlencode(grapheme_extract( $char_a_ring_nfd . $char_o_diaeresis_nfd, 1, GRAPHEME_EXTR_COUNT, 2));
?>
The above example will output:
o%CC%88
