Yes. you are right. the OpenSSL certificate contains some double-byte
characters( that's why I need use unicode, Cause I want to put Chinese
characters into Issuer and Subject attribute) also the acrobat one
include both ASCII and Unicode(double-byte Chinese characters), but when
you sign it, you only can saw the Digital Signatures only use the ASCII
code for sign, not the unicode. That's why I asked if LiveCycle Digital
Signatures support unicode pkcs #12 file or not?
