How to fix inverted curves when converting type to curves

[Fernando Marco]

Some fonts looks like this when you convert them to curves. A partial way to fix this is to use A shortcut to select nodes, and then right click the letters, going Geometry>Split Curves. For some other letters you will need to click on Geometry>Fill Gaps (i think that should be the english names, my Affinity is in Spanish), but then you have the letter R, with remains with the gap of the curve entering the stem . I cannot use Fill Gaps because it fills also the inner spaces of the R between the curve and the stem. I dont know how to fix that little detail. Any suggestion is welcome.

Try change Fill mode:
