the denite support has not be done in my PR. and maybe we should use a repo for unicode which can be used in other fuzzy layer.

[thawk]

Yes, I agree that. In my PR for Denite-sources, just 2 files are new, others are duplicated from Unite-sources. This don't conform the DRY principle. Have a standalone plugin is a better solution. And I think we can add more, like lookup the name for the current charater, to that plugin.

how about create a unicode.vim in spacevim org?

[thawk]

It sounds good. But I don't know whether it's suitable to put these Unicode files into SpaceVim.

[wsdjeg]

no, unicode.vim should be able used without spacevim.

[wsdjeg]

just think about the fuzzy layer, we should merge source into one repo.

[thawk]

I agrees to create a unicode plugin.
