Odd. That data is either

INTERLINEAR ANNOTATION TERMINATOR followed by SOH followed by another INTERLINEAR ANNOTATION TERMINATOR

or

Arabic Letter Farsi Yeh Medial Form followed by SOH followed by another Arabic Letter Farsi Yeh Medial Form

in UTF-8 encoding.

When I first saw it, I thought I recognized it as being Byte Order Marks, but a closer check showed otherwise.

Is there a way to fix this? anyone who could successfully log characters from telnet?

Here is a modified version

Note the HTTP/1.0 and the \n added to the URL. Note also that for virtual servers like mathworks and apple use, the URL form had to be sent in the GET even though in basic HTTP it should be just the resource without the "http://www.mathworks.com" .
