    Make it work on Windows
    Apparently passing :coding 'no-conversion to make-process on windows
    is essential to receive any text at all in the process filter.
    Also needed to tweak uri-to-path and path-to-uri.
    Thanks to lsp-mode.el for these hints
    * eglot.el (eglot--make-process): Pass :coding 'no-conversion to
    (eglot--path-to-uri): Add a forward slash if windows-nt.
    (eglot--uri-to-path): Remove a forward slash if windows-nt.
    (eglot--server-textDocument/publishDiagnostics): Simplify and use
