Several European languages and Japanese (Hiragana) are supported in Dasher 1.6.
To make use of Dasher with a non-English European language, you need to train Dasher with a text file full of natural writing in your language - put this file in the location input/source or input/source.txt. Make sure the "Word" option is switched off, or else replace the file input/dict with a dictionary for your language.
As a first step towards a full Japanese version of Dasher handling both Kana and Kanji, David Ward has written a Hiragana version, available in version 1.6.3 of Dasher. (NB: windows-Dasher version 1.6.8 does not support Hiragana, because of Tcl font problems; the linux version of 1.6.8 works fine in Hiragana.) Hiragana is also available in version 3.2 of Dasher.
The conversion of Dasher to Daishoya is simple: we replace the English alphabet a..z by the Hiragana alphabet, (a,i,u,e,o, ka,ki,ku,ke,ko,...); and we replace the English training text by a Hiragana document. [Unfortunately, we have not been able to find a large pure-Hiragana document, so our language model is not as well-trained as we would like.]
Two orderings of the Hiragana alphabet are available (options "japan1" and "japan2"). In "japan2 (Hiragana 60)" the diacritical marks (",o) are included as separate characters; in "japan1 (Hiragana 83)" they are integrated by including the characters , etc. in the alphabet ("pa", "ba").
As another step, on Wed 14/7/04, we added a mixed Kana/Kanji alphabet using the Jouyou Kanji. (Screenshots by T. Matsumoto) This is not the final solution!
