[luatex] to unicode / copy paste from PDF

Hello all,

I have used LuaTeX 0.79 for a while and now LuaTeX 1.07 (with my own software). I think since the switch I cannot copy & paste from PDF anymore. Now I have seen that I can set (in the font table)

tounicode = 0 (instead of 1 what I had before)

And now copy and paste seems to work fine.

Are there any drawbacks using that? Or should I take care of the to unicode mapping myself in the long run?
