Likely there are hidden control characters being carried when you cut
and paste.

I've had troubles going back and forth between DrRacket and various
unicode aware code editors - everything from syntax errors compiling
to DrRacket hanging or even crashing trying to load source files.
Inevitably it is because some hidden character(s) snuck in.

I haven't actually experienced it with cut-n-paste, but it would not
surprise me.
