# Unicode demo
#
# Mu can't read Unicode from keyboard yet, so we'll read utf-8 from disk and
# print to screen.
#
# Steps for trying it out:
#   1. Translate this example into a disk image code.img.
#       ./translate apps/ex14.mu
#   2. Build a second disk image data.img containing some Unicode text.
#       dd if=/dev/zero of=data.img count=20160
#       echo 'நட' |dd of=data.img conv=notrunc
#   3. Run:
#       qemu-system-i386 -hda code.img -hdb data.img
#
# Expected output: 'நட' in green near the top-left corner of screen
