Their use is generally discouraged because the C/POSIX + * standards do not define their semantics beyond the ASCII range, which means + * that different implementations exhibit very different behavior. + * Instead, Unicode properties should be used directly. + * + * There are also only a few, broad C/POSIX character classes, and they tend + * to be used for conflicting purposes. For example, the "isalpha()" class + * is sometimes used to determine word boundaries, while a more sophisticated + * approach would at least distinguish initial letters from continuation + * characters (the latter including combining marks). + * (In ICU, BreakIterator is the most sophisticated API for word boundaries.) + * Another example: There is no "istitle()" class for titlecase characters. + * + * ICU 3.4 and later provides API access for all twelve C/POSIX character classes. + * ICU implements them according to the Standard Recommendations in + * Annex C: Compatibility Properties of UTS #18 Unicode Regular Expressions + * (http://www.unicode.org/reports/tr18/#Compatibility_Properties). + * + * API access for C/POSIX character classes is as follows: + * - alpha: u_isUAlphabetic(c) or u_hasBinaryProperty(c, UCHAR_ALPHABETIC) + * - lower: u_isULowercase(c) or u_hasBinaryProperty(c, UCHAR_LOWERCASE) + * - upper: u_isUUppercase(c) or u_hasBinaryProperty(c, UCHAR_UPPERCASE) + * - punct: u_ispunct(c) + * - digit: u_isdigit(c) or u_charType(c)==U_DECIMAL_DIGIT_NUMBER + * - xdigit: u_isxdigit(c) or u_hasBinaryProperty(c, UCHAR_POSIX_XDIGIT) + * - alnum: u_hasBinaryProperty(c, UCHAR_POSIX_ALNUM) + * - space: u_isUWhiteSpace(c) or u_hasBinaryProperty(c, UCHAR_WHITE_SPACE) + * - blank: u_isblank(c) or u_hasBinaryProperty(c, UCHAR_POSIX_BLANK) + * - cntrl: u_charType(c)==U_CONTROL_CHAR + * - graph: u_hasBinaryProperty(c, UCHAR_POSIX_GRAPH) + * - print: u_hasBinaryProperty(c, UCHAR_POSIX_PRINT) + * + * Note: Some of the u_isxyz() functions in uchar.h predate, and do not match, + * the Standard Recommendations in UTS #18.
