But arial doesn't have chinese chars. You should use "Arial Unicode MS" with font file "ARIALUNI.TTF" - pls check first if it is installed on your PC
If you want to add Chinese to all skins and themes
I have found these folders
C:\Program Files (x86)\Team MediaPortal\MP2-Client\Plugins\BlueVision\Skin\BlueVision\fonts
C:\Program Files (x86)\Team MediaPortal\MP2-Client\Plugins\SkinBase\Skin\default\fonts
C:\Program Files (x86)\Team MediaPortal\MP2-Client\Plugins\Titanium Extended\Skin\BlueVision\themes\Titanium Extended\fonts
C:\Program Files (x86)\Team MediaPortal\MP2-Client\Plugins\WMCSkin\Skin\WMCSkin\fonts
