I am glad that your modified dictionary is working. I am still not able to do it with the Japanese dictionary. Could you tell me which dictionary you replaced? I am especially interested whether the recent (original) version consists of gzipped html files (signature 1F8B08), like the English-English dictionary, or of html files with another encoding (no signature), like the French-French dictionary.
