the first case still failed to show the correct result,
maybe I'd better wait for the arrival of the new functions after a couple of weeks.

Subject: RE: [iText-questions] How to convert extended font to CID?

What I'm going to say is valid for Acrobat in windows and you should start
there. After working there, worry about xpdf.
Acrobat has a single way to address the glyphs in the fonts with the CID
number. This is the index to the glyph.
There are a number of mappings to simplify our life. One of them is
UniCNS-UCS2-V that maps Unicode (16 bits) to CID and doesn't have all the
characters. Other encoding is HKscs-B5-H that has the mapping from the
extended big5 to the CID. This last mapping is not directly supported in
iText because big5 has 8 and 16 bit characters and that wouldn't fit in the
text strings used in Java. What is needed is a function that converts the
big5 from a byte array to a CID in a string that can then be used with the
font:
BaseFont bfChinese = BaseFont.createFont("MSungStd-Light",
BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
This function should exist in iText and if you care to wait a couple of
weeks it will be there, together with other encodings.
