Re: parser generator with DBCS option

Recently we have extended the scanner generator Rex of the Cocktail
Toolbox to generate scanners for double-byte characters and for
four-byte characters. The input stream can be encoded besides
single-byte characters in UCS-2, UCS-4, UTF-8, or UTF-16. This version
of Rex will be available with the next release of Cocktail. We are
still using the table-driven approach as before, however the
characters are mapped to index values instead of being used directly
as index into tables. For double-byte characters the mapping can be
done by accessing an array. Using this mapping the proper scanner
tables are smaller than before.
