storing data in google-drive (gdfuse - pkg=google-drive-ocamlfuse) mountpoint breaks access from Android

Trying to share a ToDo List betweeen Debian and Android.
On Debian todotxt-cli + google-drive-ocamlfuse let's me store the data in a Google-Drive folder.
All works well from either todotxt-cli - OR - Android ToDo.txt (published by Aditya Bhaskar).
But when list is edited by todotxt-clii, the todo.txt file on google-drive gets changed to mime-type = binary, which makes it invisible to the Android app. Researching this, I found similar report from someone editing google drive file with Libre Office, and suspected cause being that Libre is creating a new .tmp file for editing, then renaming it to odt (or other appropriate Libre file extension). Looking at the Google-API, appears one may explicitly set mime-type, but of course todotxt is not using the API. GDFuse is, but of course cannot assume what mime-type todotxt or Libre is going to create.
If this is indeed a problem of file extension and google assuming it be binary:
Is there possibly an other temporary file extension that might be used, which google would automatically type as plain-text?
