I have the same problem. I’ve solved it. I replace all “utf-8” with “latin-1” in shapefile.py, which located in ~/Library/Python/3.7/lib/python/site-packages/shapefile.py

Created #340 that should help fix this

Oooh, it is a bit more trickier than that. drawstates() and drawcountries() is implemented using LineCollection objects, but drawcounties() is implemented using a PolyCollection, which has a lower default zorder. This wouldn’t be too much of an issue, but because the coastline drawing is done as PolyCollection, and came after the county drawing, the coastline stuff clobbers the county polygons. Perhaps I can “fix” it by keeping the counties as PolyCollection for backwards compat, but initializing it with the default zorder of a LineCollection (which is what the documentation says it should do, anyway).

oooh, good catch! Perhaps I should update the default zorder of the county stuff so that it goes above other stuff?

It fills continents over your county boundaries (which is a bit weird)… A workaround is to use mm.drawcounties(zorder=20)

Cheers
