v0.1 by Linus Yang
In iOS 5 and below, the CoreText framework has an issue that all Chinese glyphs are shown in bold style, no matter which style you have chosen in CTFontDescriptor. (iOS 6 and above has fixed this issue.)
Detailed information please visit this page.
This Cydia tweak can fix this annoying issue below iOS 6, especially for apps like Opera Mini , which uses CoreText to render its text.
