What is Mbstring?

The Mbstring is an extension of PHP and stands for multi-byte string functions. It is basically used to represent the non-ASCII strings. As there are many languages those can be represented by one to one mapping to an 8-bit value but also some languages those require more than 8-bit mapping, thus, they need the mbstring to encode multibyte characters and express more than 256 unique value or characters in the regular bytewise coding system.
