Super simple Chinese font addon
 

Hey, looking for an addon that needs no configuration and changes all the default fonts into a font that supports both Chinese and English characters.

Surprised that I couldn't find any addon like this :/

You can replace/override your (default) fonts with chinese fonts as described on vranx

chinese fonts generally support english characters too

What you need to find isn't a specific font for Chinese characters, but one that has full Unicode support, which would include Chinese characters among others.

The simplest option is probably to extract the default fonts from the game client, rename the Chinese font files to the names of the English font files, and drop them in a Fonts folder inside your WoW folder. Every region's client includes the font files for all regions, not just its own.
