如何将非ASCII密钥与utf-8编码的.vimrc绑定？

Question

The problem

I have a Scandinavian keyboard, and I want to bind my Æ , Ø and Å keys . For example, I use Ø as leader :

" ok, works:
let mapleader = "ø"

When the .vimrc is encoded in latin1 , this works like a charm. However, I want to use :set enc=utf8 in my .vimrc , and then the mappings stop working:

" whoops, doesn't work:
let mapleader = "ø"
set encoding=utf-8

I presume this is because the .vimrc is written as utf-8, and that Vim is unable to parse or map the multi-byte characters.

What I want is to be able to use my non-ascii keymappings while still defaulting to utf-8 for all files other than .vimrc . (Storing .vimrc as latin1 would be an acceptable solution, but I haven't figured out a way to do it.)

Approaches that don't work

I have tried all kinds of things, and none of the following work:

• Modelines that set encoding and/or fileencoding for .vimrc .
• Mapping the keys to "\ø" and similar values instead.
• Putting non-valid utf-8 sequences in .vimrc to force defaulting to latin1 .
• Various autocommands to set encoding and/or fileencoding for .vimrc .
• Opening Vim with --cmd "set encoding=latin1" , because I edit my .vimrc too frequently for that to be feasible.

How can I use both set encoding=utf-8 and map my non-ascii keys?

The problem is caused by the ultisnips plugin. Disabling ultisnips will resolve the issue.
