Nerd Font rendering messed up on Windows

[Zarainia]

Describe the bug When using DejaVu Sans Mono Nerd Font, the spacing between certain symbols is too small. This is supposed to have a =: Startify recent files (those are backslashes!): I am using the same font on Linux with neovim-gtk, which I compiled myself, with the same vim configuration other than the relevant paths, and do not have this problem there. Font is set using the following line in AppData\Local\nvim\ginit.vim (changing it does work):

call rpcnotify(1, 'Gui', 'Font', 'DejaVuSansMono NF 12')

Technical information (please complete the following information):

• OS: Windows 10
• Neovim version: v0.5.0-330-g171ee46acc
• Neovim-Gtk build version: Windows "latest build" from main page, downloaded today.

This also happens in Windows Subsystem for Linux, compiled and installed on WSL Ubuntu and running using the Xming X server.
