Hi all, The documentation and help already contains this --unicode This is equivalent to --code-page=65001. Note that some devices don't support unicode maps produced by mkgmap. I added the hint while working on the optimize-index branch, it is in the branch since r3968. Please suggest improvements if this is not enough.

The warning should be for real warnings that happen because of bugs/problems.

But in any way there will be more and more people affected as the number of new Garmin devices increases. So we should issue a warning message when maps are built with the unicode option. Something like: "The use of the option unicode will cause problems on recent Garmin devices. Consider using another encoding instead." What do You think ?
