CJK support on Beepy

CJK support on Beepy (both display and input)

The Beepy uses a monochrome sharp memory LCD panel which has some caveat. This document includes a way to bring CJK support to Beepy in the framebuffer. The below is based on raspbian on raspberry pi zero, and had ran the Beepy setup script found on https://beepy.sqfmi.com/docs/getting-started.

Install DRM driver for the LCD

We will be using fbterm. Since fbterm supports minimal of 32bpp, we need to install a DRM driver for the sharp memory LCD panel to enable 32bpp mode.

Download the driver made by excel,

$ git clone https://github.com/ardangelo/sharp-drm-driver.git
