Some, but the most important one is probably that FOP implements Unicode line breaking rules,
and Unicode UAX#14 does not allow breaking before characters of class HY (such as U+002D HYPHEN-MINUS).
See: http://unicode.org/reports/tr14/#Algorithm and scroll down to find "LB21 Do not break
before hyphen-minus ..."

If you need a true line-wrapping effect, the usually suggested workaround is to inject ZWSP
into the text, either at strategically chosen locations or between every two characters/hyphens.

Andreas
