commit https://github.com/vim/vim/commit/1c39102666d2ccb998059bd7ada2d2efa31a11bc Author: Bram Moolenaar <Bram@vim.org> Date: Sun Feb 28 18:04:00 2016 +0100 patch 7.4.1450 Problem: Json encoding still fails when encoding is not utf-8. Solution: Set 'encoding' before :scriptencoding. Run the json test separately to avoid affecting other tests.
