The strangest behavior is the difference between a pure ASCII string and an UTF-8 with chars in the [80-FFFF] range. The other wrong thing is the difference of behavior between substr() and grapheme_substr(). I think substr's behavior is the good one. Test script: --------------- <?php var_dump(substr('deja', 1, -4)); var_dump(substr('deja', -1, 0)); var_dump(grapheme_substr('deja', 1, -4)); var_dump(grapheme_substr('deja', -1, 0)); var_dump(grapheme_substr('déjà ', 1, -4)); var_dump(grapheme_substr('déjà ', -1, 0)); ?> Expected result: ---------------- bool(false) string(0) "" bool(false) string(0) "" bool(false) string(0) "" Actual result: -------------- bool(false) string(0) "" bool(false) string(0) "" string(5) "éjà " bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62759&edit=1
