You may need to adjust the address of the code you are jumping to with a nop sled, if you can control the destination address (such as in the framebuffer RAM), to make it utf-8 friendly. If you are jumping to a native instruction at a known fixed address, that may be a little harder. Due to previous messages, I suspect you are targetting an existing instruction.

If it helps, this issue of Phrack is dedicated to "Writing UTF-8 compatible shellcodes":

Of course, that method will need to be adapted to the ARM instruction set...

[I suppose I need to get my hands on a KT to really be useful here, though.]
