Yes.  FileAppender's and the like will by default use the system  
default encoding which may or may not support a particular  
character.  If you are having problems with getting the expected  
characters into the output, then explicitly specify an encoding.  For  
example, "UTF-16" and "UTF-8" can represent all unicode characters  
while "ISO-8859-1" can only represent the first 256 unicode  
characters (which includes all needed for the Western European  
languages).  If you see mangled characters when you view one of 8-bit  
files ("UTF-8" or "ISO-8859-1"), it is likely due a mismatch between  
the files encoding and the encoding assumed by your editor).  You  
could avoid that problem by specifying the "UTF-16" encoding which  
would not be ambiguous, but would double the file size.
