Yes, docx softhyphens (optional word brakes), seem to look more like objects then characters. They do not react to unicode-revealing shortcut Alt+X, their "ascii value" is 31 (?), their XML representation is element <w:softHyphen/> (not character)...

My attempts to create optional word brakes using suggested Calibre "search and replace" export feature was (yet) not succesfull. Well, all I tried was replacing using expression \u200C (which is unicode value of suggested "zero width non-joiner"), and using expression \u001F (hexa value of 31)... Excuse my naive approach. : )

Possible good reason for converting soft hyphens to OWB as default Calibre export behaviour: MS Word itself is behaving that way. OWB are converted to SHY when exported to HTML, and vice versa (just tested in Word 2010).
