how to render a character with 1 pixel edge

I’ve encounter a big problem with text drawing on the screen.
using CCLabelTTF,the string on the screen is hard to recognize.
so I need to draw an edge with different color.
Is there any solution? Thanks.

P.S. I need to draw all GBK char ,so I can’t using CCLabelBMFont and CCLabelAtlas.

2dx have no feature that and render your string in blod/italic etc.
The key problem is “the string on the screen is hard to recognize”, which platform / which version of 2dx are you developing on?

I‘m using ,on android/ios platform. i’m developing a rpg game that have a complex colored background .so the strings with no solid edge is hard to recognize
