rjc put in the table for the sherlock encoding number (TEC encoding number) to charset mapping for beta1. We need to complete the implementation.
The place to change: MapEncoding() method in mozilla/xpfe/components/search/src/nsInternetSearchService.cpp
Added more mapping to the table (auto generated by TEC and xpcom alias manager). I think this is enough for the first version as we don't see many charsets support by the servers.
