Thanks for the reply.
I have read the example about embedding before posting this question. I do need
subsetting.
By analyzing the document, I have gotten the full list of the required
characters in the document. The 'NOT a trivial task' is already accomplished.
Please give me information about how to subset the needed font data into the
existing PDF document. The ToUnicode part won't be big problem. I just don't
know how to generate the appropriate FontFile2 stream.
