Examples of CP1252 and ISO-8859-1 Encodings

This section provides examples of encoded byte sequences of the JVM default encoding, CP1252 encoding, on a Windows system. The ISO-8859-1 encoding is slightly different that the CP1252 encoding.

Running the testing program with Java SE 7, EncodingSampler2.java, provided in the previous section without any argument will use the JVM's default character encoding:

C:\herong>javac EncodingSampler2.java

C:\herong>java EncodingSampler2
Default (Cp1252) encoding:
Char,     String, Writer, Charset, Encoder
00000000, 00, 00, 00, 00
0000003F, 3F, 3F, 3F, 3F
00000040, 40, 40, 40, 40
0000007F, 7F, 7F, 7F, 7F
00000080, 3F, 3F, 3F, 00
000000BF, BF, BF, BF, BF
000000C0, C0, C0, C0, C0
000000FF, FF, FF, FF, FF
00000100, 3F, 3F, 3F, 00
00003FFF, 3F, 3F, 3F, 00
00004000, 3F, 3F, 3F, 00
00007FFF, 3F, 3F, 3F, 00
00008000, 3F, 3F, 3F, 00
0000BFFF, 3F, 3F, 3F, 00
0000C000, 3F, 3F, 3F, 00
0000EFFF, 3F, 3F, 3F, 00
0000F000, 3F, 3F, 3F, 00
0000FFFF, 3F, 3F, 3F, 00
0001F108, 3F, 3F, 3F, 00
0001F132, 3F, 3F, 3F, 00
0001F1A0, 3F, 3F, 3F, 00

The results shows that:

Running the program again with 'CP1252' as the argument should give us the same output as the previous run:

C:\herong>java EncodingSampler2 CP1252
CP1252 encoding:
Char,     String, Writer, Charset, Encoder
00000000, 00, 00, 00, 00
0000003F, 3F, 3F, 3F, 3F
00000040, 40, 40, 40, 40
0000007F, 7F, 7F, 7F, 7F
00000080, 3F, 3F, 3F, 00
000000BF, BF, BF, BF, BF
000000C0, C0, C0, C0, C0
000000FF, FF, FF, FF, FF
00000100, 3F, 3F, 3F, 00
00003FFF, 3F, 3F, 3F, 00
00004000, 3F, 3F, 3F, 00
00007FFF, 3F, 3F, 3F, 00
00008000, 3F, 3F, 3F, 00
0000BFFF, 3F, 3F, 3F, 00
0000C000, 3F, 3F, 3F, 00
0000EFFF, 3F, 3F, 3F, 00
0000F000, 3F, 3F, 3F, 00
0000FFFF, 3F, 3F, 3F, 00
0001F108, 3F, 3F, 3F, 00
0001F132, 3F, 3F, 3F, 00
0001F1A0, 3F, 3F, 3F, 00

Let's try another encoding, ISO-8859-1:

C:\herong>java EncodingSampler2 ISO-8859-1
ISO-8859-1 encoding:
Char, String, Writer, Charset, Encoder
ISO-8859-1 encoding:
Char,     String, Writer, Charset, Encoder
00000000, 00, 00, 00, 00
0000003F, 3F, 3F, 3F, 3F
00000040, 40, 40, 40, 40
0000007F, 7F, 7F, 7F, 7F
00000080, 80, 80, 80, 80
000000BF, BF, BF, BF, BF
000000C0, C0, C0, C0, C0
000000FF, FF, FF, FF, FF
00000100, 3F, 3F, 3F, 00
00003FFF, 3F, 3F, 3F, 00
00004000, 3F, 3F, 3F, 00
00007FFF, 3F, 3F, 3F, 00
00008000, 3F, 3F, 3F, 00
0000BFFF, 3F, 3F, 3F, 00
0000C000, 3F, 3F, 3F, 00
0000EFFF, 3F, 3F, 3F, 00
0000F000, 3F, 3F, 3F, 00
0000FFFF, 3F, 3F, 3F, 00
0001F108, 3F, 3F, 3F, 00
0001F132, 3F, 3F, 3F, 00
0001F1A0, 3F, 3F, 3F, 00

ISO-8859-1 encoding is different than CP1252 encoding. As you can see in the output, 0x80 is a valid character in the ISO-8859-1 character set, but not valid in the CP1252 character set.
