Even for single words such translators are not really good, in most cases it only gives you an idea of what it could be. That can help when understanding someone, but if you would see it in the game you would get spasms or so
For graal kingdoms we made a new translation system that uses tools like gettext and poedit, might be possible to enable it for playerworlds someday too, but would need some work. There is a command line script that extracts all say2's, messages and text in #U(), which then needs to be translated, and depending on the language you choose in the starting screen the npcserver replaces the text with the translation so that you see the translated text.
