UnicodeToBytes.java (write(String,int,int,char[])): New overloading, allows greater efficiency.

�
	* gnu/gcj/convert/UnicodeToBytes.java (write(String,int,int,char[])):
	New overloading, allows greater efficiency.
	* gnu/gcj/convert/Output_8859_1.java (write(String,int,int,char[])):
	New overloading (for efficiency - avoids copying).
	* gnu/gcj/convert/Output_UTF8.java:  Fix typo: 0xC0 -> 0c3F.
	* gnu/gcj/convert/Input_UTF8.java:  Fix typos in bit masks.
