Thanks at lot. So char has a bug. Or maybe the problem lies even deeper:

octave:39> c=["a";"b";"";"d"]
c =

a
b
d

Is that compatible behaviour?

Could some of the c++ gurus help with this, please? I have tried to find what happens in the source
code but got terribly lost in all these overloaded methods for convert_to_str_internal (even with
the help of doxygen).
