Two sample equivalent text strings.
 
 
Three TextWriter variables ...
 
 
for ISO Latin 1,
 
 
 
UTF-8,
 
and UTF-16 StreamWriter objects.
The static types of all variables are
TextWriter. The dynamic types are
all StreamWriter. This is typical!
Systematiclaly, write both str and
strEquiv to all three StreamWriters.
 
 
Close all StreamWriters.
