See the UChar API docs for details. - * - * UChar32 is defined to be a signed 32-bit integer (int32_t), large enough for a 21-bit - * Unicode code point (Unicode scalar value, 0..0x10ffff) and U_SENTINEL (-1). - * Before ICU 2.4, the definition of UChar32 was similarly platform-dependent as - * the definition of UChar. For details see the documentation for UChar32 itself. - * - * utf.h defines a small number of C macros for single Unicode code points. - * These are simple checks for surrogates and non-characters. - * For actual Unicode character properties see uchar.h. - * - * By default, string operations must be done with error checking in case - * a string is not well-formed UTF-16 or UTF-8. - * - * The U16_ macros detect if a surrogate code unit is unpaired - * (lead unit without trail unit or vice versa) and just return the unit itself - * as the code point. - * - * The U8_ macros detect illegal byte sequences and return a negative value. - * Starting with ICU 60, the observable length of a single illegal byte sequence - * skipped by one of these macros follows the Unicode 6+ recommendation - * which is consistent with the W3C Encoding Standard. - * - * There are ..._OR_FFFD versions of both U16_ and U8_ macros - * that return U+FFFD for illegal code unit sequences. - * - * The regular "safe" macros require that the initial, passed-in string index - * is within bounds. They only check the index when they read more than one - * code unit. This is usually done with code similar to the following loop: - * 
while(i
- *
- * When it is safe to assume that text is well-formed UTF-16
- * (does not contain single, unpaired surrogates), then one can use
- * U16_..._UNSAFE macros.
- * These do not check for proper code unit sequences or truncated text and may
- * yield wrong results or even cause a crash if they are used with "malformed"
- * text.
- * In practice, U16_..._UNSAFE macros will produce slightly less code but
- * should not be faster because the processing is only different when a
- * surrogate code unit is detected, which will be rare.
- *
- * Similarly for UTF-8, there are "safe" macros without a suffix,
- * and U8_..._UNSAFE versions.
- * The performance differences are much larger here because UTF-8 provides so
- * many opportunities for malformed sequences.
- * The unsafe UTF-8 macros are entirely implemented inside the macro definitions
- * and are fast, while the safe UTF-8 macros call functions for some complicated cases.
- *
- * Unlike with UTF-16, malformed sequences cannot be expressed with distinct
- * code point values (0..U+10ffff). They are indicated with negative values instead.
- *
- * For more information see the ICU User Guide Strings chapter
- * (http://userguide.icu-project.org/strings).
- *
- * Usage:
- * ICU coding guidelines for if() statements should be followed when using these macros.
- * Compound statements (curly braces {}) must be used  for if-else-while... 
- * bodies and all macro statements should be terminated with semicolon.
