RMPrepUSB INI files can specify the Locale ID (LCID), the font name and the Character Set, as well as the font sizes for the button, label and help text. INI files should be saved as UniCode.

if possible, test out your INI file on as many different systems as possible.

Note: For Windows XP, you must install Asian Language support in order to view Chinese and other languages (via Control Panel).

An example is shown below for Chinese Simplified

LCID=2052
HelpFontName=SimSun

HelpFontBold=false

Here is an example for Chinese Traditional
