What is the ID length limit of Wechat's temporary QR code scene with parameters?

it is said in the document that when using a value of string type as the scene ID, the length is 1 to 64, but I can still create it with a string of more than 100 bits, and the EventKey is the same as the set value after scanning the code. So what is the maximum length of scene_str? I created it with a test official account. Will the official account be different?
