Just a furter remark: while zero-width-spaces can be used as a

will mess up hyphenation in latex. I think if read somewhere that those 
can be removed with hooks or filters, but I think that shouldn't be 
necessary.
Can you create an example of such scenario and post it as a bug?
Probably, we just need to strip all zero-width spaces at the basic ox.el
level.
To be clear: That's not an org bug. It's just that latex won't be able such a word. If | is a zero width space, the word "hyphen|ation" is not the same as "hyphenation".
1. hyphenation
2. hyphen|ation
