I know that this has been asked before and that the rational for not implementing it is to keep the code base small. I do respect that but Decker becomes much less accessible for users (especially kids) with other languages than English. In Sweden and Finland, for example, we use åäö and there has been other posts about French and Japanese.
How much of a re factoring of the code would be needed to add UTF-8 support (or legacy or multi-byte encoding)?
