New Comment:
I can confirm this bug, but I'm not sure how to fix it correctly. If I fix the
related logic, the substr tests then partially fail. This function is cryptic
and
should really deserve some comments about what means each variable name and
what
are their goals...

Description:
------------
If the input string contains multibyte characters and the length argument is
greater then the possible maximum length of the result the function returns
false.
Test script:
---------------
<?php
var_dump(
grapheme_substr('FOK', 1, 20), // expected: OK
grapheme_substr('íêµì´', 1, 20) //expected: êµì´
);
Expected result:
----------------
string(2) "OK"
string(6) "êµì´"
Actual result:
--------------
string(2) "OK"
bool(false)
