This library is a C interface to the Unicode Characters Database. It delivers most, but not all information from the UCD, the chief omissions are the UniHan database and (currently) the non-simple case transformations. If you're using this, please drop me (H. Peter Anvin ) a note; probably there will eventually be a mailing list. To compile, adjust the file MCONFIG to suit your needs, and build it with "make". See the man page (libucd.3) and the header file (ucd.h) for API information.
