Their use is generally discouraged because the C/POSIX 68 * standards do not define their semantics beyond the ASCII range, which means 69 * that different implementations exhibit very different behavior. 70 * Instead, Unicode properties should be used directly. 71 * 72 * There are also only a few, broad C/POSIX character classes, and they tend 73 * to be used for conflicting purposes. For example, the "isalpha()" class 74 * is sometimes used to determine word boundaries, while a more sophisticated 75 * approach would at least distinguish initial letters from continuation 76 * characters (the latter including combining marks). 77 * (In ICU, BreakIterator is the most sophisticated API for word boundaries.) 78 * Another example: There is no "istitle()" class for titlecase characters. 79 * 80 * ICU 3.4 and later provides API access for all twelve C/POSIX character classes. 81 * ICU implements them according to the Standard Recommendations in 82 * Annex C: Compatibility Properties of UTS #18 Unicode Regular Expressions 83 * (http://www.unicode.org/reports/tr18/#Compatibility_Properties). 84 * 85 * API access for C/POSIX character classes is as follows: 86 * - alpha: u_isUAlphabetic(c) or u_hasBinaryProperty(c, UCHAR_ALPHABETIC) 87 * - lower: u_isULowercase(c) or u_hasBinaryProperty(c, UCHAR_LOWERCASE) 88 * - upper: u_isUUppercase(c) or u_hasBinaryProperty(c, UCHAR_UPPERCASE) 89 * - punct: u_ispunct(c) 90 * - digit: u_isdigit(c) or u_charType(c)==U_DECIMAL_DIGIT_NUMBER 91 * - xdigit: u_isxdigit(c) or u_hasBinaryProperty(c, UCHAR_POSIX_XDIGIT) 92 * - alnum: u_hasBinaryProperty(c, UCHAR_POSIX_ALNUM) 93 * - space: u_isUWhiteSpace(c) or u_hasBinaryProperty(c, UCHAR_WHITE_SPACE) 94 * - blank: u_isblank(c) or u_hasBinaryProperty(c, UCHAR_POSIX_BLANK) 95 * - cntrl: u_charType(c)==U_CONTROL_CHAR 96 * - graph: u_hasBinaryProperty(c, UCHAR_POSIX_GRAPH) 97 * - print: u_hasBinaryProperty(c, UCHAR_POSIX_PRINT) 98 * 99 * Note: Some of the u_isxyz() functions in uchar.h predate, and do not match, 100 * the Standard Recommendations in UTS #18. Instead, they match Java 101 * functions according to their API documentation. 102 * 103 * \htmlonly 104 * The C/POSIX character classes are also available in UnicodeSet patterns, 105 * using patterns like [:graph:] or \p{graph}. 106 * \endhtmlonly 107 * 108 * Note: There are several ICU whitespace functions. 109 * Comparison: 110 * - u_isUWhiteSpace=UCHAR_WHITE_SPACE: Unicode White_Space property; 111 * most of general categories "Z" (separators) + most whitespace ISO controls 112 * (including no-break spaces, but excluding IS1..IS4 and ZWSP) 113 * - u_isWhitespace: Java isWhitespace; Z + whitespace ISO controls but excluding no-break spaces 114 * - u_isJavaSpaceChar: Java isSpaceChar; just Z (including no-break spaces) 115 * - u_isspace: Z + whitespace ISO controls (including no-break spaces) 116 * - u_isblank: "horizontal spaces" = TAB + Zs - ZWSP 117 */ 118 119 /** 120 * Constants. 121 */ 122 123 /** The lowest Unicode code point value.
