It would actually be extremely convenient to emit an empty box (word) instead.  
I'm unsure that a crash is helpful.

One use case is splitting words by parentheses groups (without the outter 
parentheses), such that only odd indexes are paren groups.  The workaround is 
to append an empty box if leading char is (, and to replace ')(' (consecutive 
close then open) strings with a sequence of nulls long enough to not have 
likely occurred with natural probability.

setting j=0 on start is not allowed, because it must be smaller than i.

ew on first char ( (empty word) would work well.  Because I wish to discard 
closing ), ew on immediately following ( (again empty word) with a (
