# 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
