UniChar, A 16-bit Unicode code value in the default UTF-16 format. UTF16Char UnicodeScalarValues 0-0xFFFF are expressed in UTF-16 format using a single UTF16Char with the same value. UnicodeScalarValues 0x10000-0x10FFFF are expressed in UTF-16 format using a pair of UTF16Chars - one in the high surrogate range (0xD800-0xDBFF) followed by one in the low surrogate range (0xDC00-0xDFFF). All of the characters defined in Unicode versions through 3.0 are in the range 0-0xFFFF and can be expressed using a single UTF16Char, thus the term "Unicode character" generally refers to a UniChar = UTF16Char. UTF8Char An 8-bit code value in UTF-8 format. UnicodeScalarValues 0-0x7F are expressed in UTF-8 format using one UTF8Char with the same value. UnicodeScalarValues above 0x7F are expressed in UTF-8 format using 2-4 UTF8Chars, all with values in the range 0x80-0xF4 (UnicodeScalarValues 0x100-0xFFFF use two or three UTF8Chars, UnicodeScalarValues 0x10000-0x10FFFF use four UTF8Chars).

A pascal string does not have a termination byte. A pascal string can hold at most 255 bytes of data. The first character in a pascal string is offset one byte from the start of the string. A C string is terminated with a byte of value zero. A C string has no length limitation. The first character in a C string is the zeroth byte of the string. *********************************************************************************/ typedef UInt32 UnicodeScalarValue; typedef UInt32 UTF32Char; typedef UInt16 UniChar; typedef UInt16 UTF16Char; typedef UInt8 UTF8Char; typedef UniChar * UniCharPtr; typedef unsigned long UniCharCount; typedef UniCharCount * UniCharCountPtr; typedef unsigned char Str255[256]; typedef unsigned char Str63[64]; typedef unsigned char Str32[33]; typedef unsigned char Str31[32]; typedef unsigned char Str27[28]; typedef unsigned char Str15[16]; /* The type Str32 is used in many AppleTalk based data structures.
