解法：先使用 fontmake -h 查看沒有可以使用的參數，找到關於 overlaps
Handling of contours:
--keep-overlaps Do not remove any overlap.
--overlaps-backend BACKEND
Select library to remove overlaps. Choose between:
booleanOperations, pathops (default:
booleanOperations)
由於 pathops 在 python2 已無法使用，python3 的安裝方法：
pip3 install --upgrade skia-pathops
由於直接執行 fontmake 會使用 python2 來執行，所以指令改成：
python3 -m fontmake
在 python3 使用 booleanOperations

改用 pathops，一樣有錯誤：
