What PHP characters will affect the parsing of unserialize?

Upstairs positive solution
For example, UTF-8 encoding

Echo serialize ('my'); // output: s: 3: "my ";

Under gbk encoding

Echo serialize ('my'); // output: s: 2: "my ";

So you can never serialize the three-byte 'my' encoded by utf8 and parse it in the deserialization mode of gbk encoding.

I think it should be caused by inconsistent encoding during data serialization and deserialization, or you can paste an incorrect statement for analysis.
