Unicode

Unicode defines a 31-bit character set. A font is considered to be Unicode if it contains characters outside the ASCII character set.

Unicode code characters in a font are encoded using the UTF-8 format in the font metrics file.

RenderWare Graphics supports Unicode through the Rt2d toolkit. Font formats are saved in .met file format in UTF-8 format.

UCS

UCS contains all character set standards. It is based on 4 bytes per character (32-bit) coding scheme with 2 byte per character (16 bit) coding scheme forms the bitmap (UCS-2).
