mb_strcut() returns the portion of
str specified by the
start and
length parameters.
mb_strcut() performs equivalent operation as
mb_substr() with different method. If
start position is multi-byte character's
second byte or larger, it starts from first byte of multi-byte
character.
It subtracts string from str that is
shorter than length AND character that is
not part of multi-byte string or not being middle of shift
sequence.
encoding is character encoding. If it is
not set, internal character encoding is used.
