I'm not tcl/tk expert, so probably missng many things. :-(
Can you explain how to solve this issue by moving to Tcl_CreateObjCommand?

I created adhok.patch just for explanation. This is not solution. I used
Tcl_CreateObjCommand + Tcl_GetUnicode to demonstrate Tcl converts
'\xc0\x80' to null byte. (adhok.patch contained Japanese characters, so
I'll repost that as just_for_explanation.patch)
