Window Swtiching Mappings Not Working

Question

To make things a bit quicker, I've remapped the window switching commands like this:

nnoremap <silent> <C-j> <C-w>j
nnoremap <silent> <C-k> <C-w>k
nnoremap <silent> <C-h> <C-w>h
nnoremap <silent> <C-l> <C-w>l

My goal is to type <C-j>, <C-k>, etc., to switch between window splits. The <C-j> and <C-k bindings work, but for some reason <C-h> and <C-l> don't do anything. <C-w>h and <C-w>l work as expected.

If I run :nmap, I see the following for those commands:

...
n  <C-H>       * <C-W>h
n  <NL>        * <C-W>j
n  <C-K>       * <C-W>k
n  <C-L>       * <C-W>l
...

I'm using Neovim 0.1.4

Edit

I mispoke earlier. It looks like <C-l> is working as well. That just leaves <C-h> not working.

After digging into this some more, it looks like this is a known issue with Neovim and tmux. iTerm2 is interpreting <C-h> as a backspace and sending that instead. As a workaround, I've mapped backspace to to the action I want:

if has('nvim')
  nnoremap <bs> <C-w>h
endif
