Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_06-b05, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Linux ifs.dk 2.6.14-1.1644_FC4 #1 Sun Nov 27 03:24:54 EST 2005 x86_64 x86_64 x86_64 GNU/Linux


A DESCRIPTION OF THE PROBLEM :
If a utf-8 coded text represent diacriticals, for example ä or ÃÂ¥ as combining diacriticals (so it is apparently called). This means ÃÂ¥ for example is represented as 'a' and codepoint 0x308 (COMBINING RING ABOVE).

But when saving as iso-8859-1 these 2 are saved as 2 separate characters: a and something strange; not as the correct 'ÃÂ¥'.

input file: eksempel.txt (utf-8)
program: t.java

produces out.txt (iso-8859-1)


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
(will attach input / or mail on request)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
abc äëö abc/
abc è abc/
abc æøÃÂ¥ abc/

ACTUAL -
abc a?e?o? abc/
abc è abc/
abc æøa? abc/


REPRODUCIBILITY :
This bug can be reproduced always.
