I've consulted some typography books: The Chicago manual of style [1] doesn't mention such a rule at all. Dowding [2] mentions it, but only for ragged-edged columns, not for justified ones (also the book doesn't follow such a rule for its own text). However, the main point is that the document will be processed automatically with very little human intervention. So we shouldn't take away too many possible break points from TeX, otherwise we risk uneven spacing or overfull hboxes. > But sure I can if you can tell me when to use it. So far, the only places where ~ is used is for cross references, i.e. between the word "section", "table", etc., and the following number (specified by \ref).
