FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)
FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]
Service Pack 2
A DESCRIPTION OF THE PROBLEM :
WHen I try to create strings in the default character
set, "Cp1252", I can't create strings for characters 128
through 159.
For example 153 which is, according to all sources I have
found, the trademark character in Cp1252. If I create a
byte array as {-103}, and create a string from it in the
default character set, the character returned is " And If
I specifically create a string in ISO-8859-1 with the TM
character, and I run str.getBytes(), the TM character is
converted to ?, which is byte value 63.
REGRESSION. Last worked in version 1.1.8
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.create a byte array as {-103}
2.create a string from it in the default character set
3.character returned is ", should be TM.
4.create a string in ISO-8859-1 with the TM character
5.call str.getBytes() to get a byte array
6.create a string from it in the default character set
7.byte's value is 63, should be -103
EXPECTED VERSUS ACTUAL BEHAVIOR :
The TM character was turned into a ? because java thought
cp1252 didn't have the TM character, and the byte value of -
103 was interpreted as the " charcter.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
no exceptions
This bug can be reproduced always.
