Localization in NGUI

As far as I know, if I want to use localization for UILabel in NGUI, I have to assign a font to that NGUI.

What if I have 2 different fonts (for different languages)? Since I use Font Maker in NGUI to create the font with dynamic type (.tff files), so I have 2 different .tff files and so 2 different font prefabs. Do I need to write extra script to change the font that UILabel is using? Or any better method?

Thanks for help.
