我手动修改PDF并需要更新名称词典。有一个类似于以下的对象编码我认为是嵌入文档的文件名：

这是什么类型的编码？：
<FEFF003C00320030003E0061002E006A00700067>26 0 R
我能够使用pdftk查看上面的哈希：
(þÿ^@<^@2^@0^@>^@a^@.^@j^@p^@g) 26 0 R
我可以看到这在视觉上表示类似于：（＆lt; 20＆gt; a.jpg）26 0 R - 哪个cdorrespond到ojbect 26
我希望能够解密/解压缩此对象，手动修改它，然后将其添加回PDF（或类似的东西并修改外部参照表等）。
提前谢谢
答案 0 :(得分：1)
你叫什么＆＃34;哈希＆＃34;是UTF-16BE编码的Base64编码字符串。
通常，您不应该手动修改PDF，因为它是二进制文件格式。
