Detailed Description

MiniGUI uses a Uint32 value to store the type information of a character.

MiniGUI uses the lower 16-bit integer for the basic type of an abstract character. The definition macros have ACHAR_BASIC_ as the prefix.

For a UNICODE character, MiniGUI uses the high 16-bit for the general UNICODE character categories and the possible line break classifications. The low byte for the general category, and the high byte for the break class.
