Comment 9 for bug 1173571

I think that my title is not well described and does not fit my idea well, so I change that.

Maybe that mislead readers to think that I was asking to add those outdated settings about Micro Hei back in language-selector confs, but that's not. To be clear, I just want to make Micro Hei back as the default Chinese character displaying font for sans-serif and monospace as it was.
