Patch to add support for Unicode BMP plane (Plane 0) on Linux fbcon TTY

Patch instructions

Original post was once lost and need to search it again on Google's cache, so here are the basic instructions to update the patch for upcoming Linux kernel versions:

Get Linux kernel source code. Linux kernel commits history is HUGE, so we only fetch the only last one:
```
git clone --branch v4.8 --depth 1 https://github.com/torvalds/linux.git
```

Test the patch:

cd linux
git apply --whitespace=warn --stat < /path/to/cjktty.patch
git apply --whitespace=warn --check < /path/to/cjktty.patch

Fix patch until there's no failures

Apply the patch and let it auto-adjust:

git apply --whitespace=warn < /path/to/cjktty.patch

Commit the changes of the patch:

git add .
git commit -m "cjktty patch for Linux 4.8.1"

Extract the patch after applied to the kernel:
```
git diff HEAD~1 -- > cjktty.patch
```
