Different versions of PHP output different results #7

I tested "Base85" on PHP 5.X and PHP 7.X. The result of PHP 5.X seems to be abnormal. To find out the cause of the problem, I tested more text. The conclusion is as follows:

Decoding all successful
Encoding in PHP 5.X is abnormal
English character encoding succeeded
Japanese and Chinese character encoding is abnormal
Invisible characters are generated, but the English part is normal

The problem seems to be in unpack("N*", $data) ? I'm confused about it.

Just to be sure, problem exists only with PHP 5.X?

Yeah.
