我试图找出字符串的pre-base64编码统计数据以及用于编码它的算法，这样我就可以编辑解码的json字符串，然后用相同的编码重新编码。
我能够解码原文。但我无法复制编码。

注意：文本开头有一个ACK字符。
我尝试了几种字符集和编码组合。主要是UTF-16（大端，小端，有和没有字节顺序标记）因为我怀疑由于长度的符号是16位。
有没有办法轻松找出字符集和编码以及是否有特定的base64实现？
答案 0 :(得分：0)
我想通过使用标准的python base64进行解码。我试过的所有java库都忽略了每个字节填充的一堆0x00字节。
事实证明，由于某些原因，我从未设法推理使用带有0x00填充的Latin1。
