commit https://github.com/vim/vim/commit/ae8eb3ca927f1b0ac2a6643da8699538cdc380f6 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Feb 7 21:59:26 2016 +0100 patch 7.4.1288 Problem: ch_sendexpr() does not use JS encoding. Solution: Use the encoding that fits the channel mode. Refuse using ch_sendexpr() on a raw channel.
