ORBIT 8-bit/16-bit Strings

["Beutner, Rolf" <Rolf Beutner t-systems de>]

Hello List,
I communicate with another ORB (Visibroker), call some methods with "String"-Parameters and have a problem
to transfer 8-bit-chars > 0x7f.
The hex-code of the chars:

Sign, Hex-Code 
ä     E4
ö     F6
ü     FC
Ä     C4
Ö     D6
Ü     DC
ß     DF

If I transfer
"a;b;c;ä;ö;ü" the other side gets (hex-coded) "61;62;63;ffe4;fff6;fffc;"
so the characters greater than 0x7F are coded in 16 bit.

Is it possible to prevent this, to just transfer 8bit-chars?

Regards
  Rolf Beutner
