Hello, David

I use jca-jdbc driver in my projects. Nice thing, but I step in a bug with
encodings (Cp1251 in my case).
The bug is: driver depends on operating system locale.
I've look in sources, and I think that problem is in
org.firebirdsql.jgds.XdrOutputStream class in this fragment:

public final void writeString(String s) throws IOException {
byte[] buffer = s.getBytes();

This will convert String into byte array with default system encoding, but
the requied encoding may be different, as in my case (my Linux uses KOI8-U,
but database use WIN1251).

When I change source and recompile driver, all was fine:

public final void writeString(String s) throws IOException {
byte[] buffer = s.getBytes("Cp1251");

I hope, this will be corrected in release or next beta of jca-jdbc driver.

Please sorry for my terrible English (my lang. is Russian:).

Good bye.
