VoiceOver in Cantonese is unable to speak the pattern /百分之[0-9]+/, i.e. Chinese percentage, e.g. "百分之10", "百分之20", "百分之1000", etc.
- Change Language to 繁體中文 (Traditional Chiense)
- Visit http://www.hko.gov.hk/textonly/v2/forecast/ndayc.htm in Safari
- Turn on VoiceOver with Default Dialect set to 中文 (廣東話) (Chinese (Cantonese))
- Use Rotor to change reading style to line by line
- Swipe down and VoiceOver reads every line except lines like "相 對 濕 度 ： 百 分 之 80 至 95 。", which contains the pattern /百分之[0-9]+/

Similar problem occurs in OS X 10.9.2. After execute the command say -v Sin-Ji "百分之10", no sound is produced.
