in neovim-qt "<" writes "<t_ü><"

Hi @junegunn,

In [neovim-qt](https://github.com/equalsraf/neovim-qt), if I type / to start a search and then press <, a bunch of control chars appear. The screenshot shows the chars correctly (Not the ones in the title, although they are a copy/past).

It is worth mentioning that this only happens in **neovim-qt**. In terminal, iTerm, or [Neovim-dot-app](https://github.com/rogual/neovim-dot-app) this does not happen.

I know this has to be a _neovim-qt_ issue. However, I was wondering if there was anyway I can remap those chars to just "<"?
I tried to add **"remap": {"X": "Y"}** dictionary to opts in https://github.com/junegunn/vim-oblique/blob/master/plugin/oblique.vim#L441. However, nothing happened :(

Maybe I don't understand how remap is supposed to be used. I was under the impression that after **/** (Oblique search forward) if you type **X** it should type **Y**.

In command area (:cmd) if I type `^v<` I get `` instead of `<`.

This happens for any plugin that uses **vim-pseudocl**, like FNR, vim-oblique etc.
