I send you this message because i think that sakura editor is a great program and i would like to see it in other languages like english, french, german and spanish. I'm the one who translates Dev-C++ to spanish (and many others) and i want to help this project to be useful for more people.
Say me if i can help or not but reply because i post a request like other guy who can translate it to other language (i'm not alone) and anyone has answer me.

Thanks for all,
Fernando.

どうしたものでしょうか．とりあえず返事をしないと．

個人的には，こうもメッセージがソースの中に埋め込まれた状態では多言語化は無理だろうと思っています．内部コードがSJISなのは仕方がないとしてもメッセージくらいは全部リソースに移動しますかねぇ．
