Invalid URI : ^A

_Actual problem_:
Can install my plugins no problem. Can not update them, their URI then becomes "^A". The **error message**:

x vim-addon-mw-utils:
Invalid URI: ^A
Expected: https://git::@github.com/MarcWeber/vim-addon-mw-utils.git
PlugClean required.
[...]

**Image**:

Tried PlugClean then PlugInstall again. Tried specifying the adresses of the github repositories with their SSH key instead.

**Part of my vimrc:**
```vim
`if has('win32')
set shell=powershell
endif
