# This example illustrates how to create Unicode text and how to embed composite fonts.
# Note: This demo assumes that 'arialuni.ttf' is present in '/Samples/TestFiles' 
# directory. Arial Unicode MS is about 24MB in size and it comes together with Windows and 
# MS Office.
# For more information about Arial Unicode MS, please consult the following Microsoft Knowledge 
# Base Article: WD2002: General Information About the Arial Unicode MS Font
# For more information consult: 
# In case you don't have access to Arial Unicode MS you can use cyberbit.ttf 
# ( instead.
