/*in order to prevent a char from be splitted into 2 blocks
We have to get the right bound of a string in terms a block
Take "我爱你" as an example
if len_limit_in_byte = 8 which means that the max size of a block is 8 Bytes
since '我' and '爱' takes 6 Bytes in total already.
and '你' takes 3 Bytes.
if we assign the '你' to the block
then the total length will be 9 which is greater than 8
so , byte_num = 6 and char_num = 2 will be returned.
and '你' has to be assigned to another block.
Please note that:
