base64encode command will change multibyte string into unicode string first, and then do the encoding

[jjsty1e]

for example(Chinese words):

百度

command: StringEncoding: Base64 Decode, got:

XHU3NjdlXHU1ZWE2

actually it's the result of \u767e\u5ea6, the right result is below:

55m+5bqm

or maybe we don't need this raw unicode encoding?
