In a previous entry I wrote about how the bone radical is written differently in some Chinese cases. Well, thanks to John H. Jenkins of Apple I found out that the People's Republic of China made a switch from the traditional character to the one that has the corner on the left side. This way the stroke count is reduced by one. But for font designers it offers a small problem, since it means that you have to know your target audience quite well.

To sum it up: PRC uses the newer character, most likely Singapore does so too being another simplified Chinese user. Hong Kong, Japan, Korea, Macao, and Taiwan use the older character.
