[datatable-help] Merging strings claim that the encodings don't match

[Matt Dowle]

Think you may have ended up with some strings internally marked ASCII by 
R,  which Encoding() returns as "unknown".  That shouldn't be a problem 
and they should join fine.   I've change the new warning in v1.8.11 so 
if it was that, it should be ok now (commit 1153), please confirm.
