xCJK2uni
========

The `xCJK2uni` package provides commands to convert CJK character to Unicode in
non-UTF-8 encoding. It provides hooks for `hyperref` to get the correct bookmarks.
It also provides some `/ToUnicode` mapping file for CJK subfont. They can be used
with `cmap` package and make CJK character searchable and copyable in PDF files
generated by pdfLaTeX.

Basic Usage
-----------

The package provides the following macros:

    \useCJKencmap{<encoding>}

Set the current encoding. The default encoding is GBK.

    \CJKchartouni{<character>}

Convert a single CJK character to its Unicode.

    \CJKsfdtouni{<plane>}{<slot>}

Convert the .sfd coordinate to its Unicode.

You can read the package manual (in Chinese) for more detailed explanations.
