getBytes() uses the JVM's default encoding to translate the String to
bytes.. This is usually something like ISO-8859-1, which is a
one-byte-per-character encoding that can't represent Hebrew letters.
If you want to generate a representation in a particular encoding (e.g.
your description implies you're expecting a particular
2-byte-per-character encoding) then you should use the getBytes()
variant that takes an encoding name.
This is not something specific to JDBC, it's standard Java. If you are
working with characters beyond 7-bit US-ASCII, I'd strongly recommend
doing some research into Java's internal string representation and how
that is transformed into bytes .. The javadoc for Charset is one
starting point:
