Re: Encoding conversion from UTF to ISO-8859-7

Hello all,

I have a problem with some encoding conversion from UTF to ISO-8859-7 .
My Oracle database uses UTF but some POS printers in the organization
use ISO-8859-7, so I need to print some Greek characters.

This is part of the code:

Charset set7 = Charset.forName("ISO-8859-7");
ByteBuffer BBtext3 = null,

tempDB = rs.getString(1); //The string in Greek. Oracle UTF
BBtext3 = set7.encode(tempDB); //The string in Greek ISO-8859-7

When I debug this code I see that BBtext3 has these values:
[0] = -51
[1] = -59
[2] = -45
and so on

If I add 256 to those numbers I get:
[0] = 205
[1] = 197
[2] = 211
Which are the positions in ISO-8859-7 of the Greek letters of the UTF
text.

If I send the original string to the printer I get '?' because there is
no such thing as character -51.

Huh?
How are you sending 'the original string'? I would expect that the
printer is merely going to receive a string of octets ; it doesn't
matter if we think of them as signed (which java does) or unsigned
(which the printer does); the pattern of bits is the same.
I guess the issue is how to send that byte stream to the printer
without it getting translated.


What am I missing? How can I complete the conversion from UTF to
ISO-8859-7? It seems that I'm half the way.

Thanks a lot for your time.
