This is the gsoc-2011 project to clean up and backport multibyte support from other nvi forks in a form we can use. USE_WIDECHAR is on unless building for the rescue crunchgen. This should allow editing in the native locale encoding. USE_ICONV depends on make.conf having 'WITH_ICONV=YES' for now. This adds the ability to do things like edit a KOI8-R file while having $LANG set to (say) en_US.UTF-8. iconv is used to transcode the characters for display. Other points: * It uses gencat and catopen/etc instead of homegrown msg catalog stuff. * A lot of stuff has been trimmed out, eg: the perl and tcl bindings which we could never use in base anyway. * It uses ncursesw when in widechar mode. This could be interesting. GSoC info: http://www.google-melange.com/gsoc/proposal/review/google/gsoc2011/zy/1 Repo at: https://github.com/lichray/nvi2 Obtained from: Zhihao Yuan <lichray@gmail.com>
