YES, YES, YES....
( - are they really going to follow up my idea ???? )
We seem to have the coding base right - while I have to rerun several tests.
It did seem to handle my other languages in this long "sort of English Duokan", and I have just tested a few more:
Icelandic, Polish, Czech, Hebrew, Greek, Maori, Japanese, Tagalog
the exception turned out to be Hebrew, BUT the layout of the text I tried did seem somewhat funny. So, no definitive answer yet.
( I cannot wait to see how it will work alongside the regular Duokan, but I may have screwed up something as that part don't seem active anymore. Should there have been a merger of the folders ? )
