char32_t Unicode Utilities

Description

A set of utility functions for identifying Unicode traits of char32_t code points.

Unicode Utility Functions

• string to_string( char32_t c ) – Returns a string containing the code point c.
• bool u_isUpperCase( char32_t c ) – Returns true if the code point c is an upper case letter character (equivalent to java.lang.Character.isUpperCase()).
• bool u_isLowerCase( char32_t c ) – Returns true if the code point c is a lower case letter character (equivalent to java.lang.Character.isLowerCase()).
• bool u_isSpace( char32_t c ) – Returns true if the code point c is a white space character; similar to C/POSIX isspace().
• bool u_isSpaceChar( char32_t c ) – Returns true if the code point c is a space character (equivalent to java.lang.Character.isSpaceChar()).
• bool u_isWhitespace( char32_t c ) – Returns true if the code point c is a white space character (similar to java.lang.Character.isWhitespace()).
• bool u_isLetter( char32_t c ) – Returns true if the code point c is a letter character (equivalent to java.lang.Character.isLetter()).
• bool u_isDigit( char32_t c ) – Returns true if the code point c is a digit character (equivalent to java.lang.Character.isDigit()).
• bool u_isLetterOrDigit( char32_t c ) – Returns true if the code point c is an alphanumeric character (letter or digit) (equivalent to java.lang.Character.isLetterOrDigit()).
• bool u_isPunctuation( char32_t c ) – Returns true if the code point c is a punctuation character.
• bool u_isBMP( char32_t c ) – Returns true if the code point c is in the Unicode Basic Multilingual Plane.
• bool u_isGraphic( char32_t c ) – Returns true if the code point c is a "graphic" character (printable, excluding spaces).
• bool u_isPrintable( char32_t c ) – Returns true if the code point c is a printable character.
• bool u_isBlank( char32_t c ) – Returns true if the code point c is a "blank" or "horizontal space", a character that visibly separates words on a line.
• bool u_isDefined( char32_t c ) – Returns true if the code point c is "defined", which usually means it is assigned a character in Unicode (equivalent to java.lang.Character.isDefined()).
• int u_charType( char32_t c ) – Returns the Unicode general category of the code point c (equivalent to java.lang.Character.getType()). Return value can be tested against UnicodeCharTypeConstants. See UnicodeCharTypeConstants.
• int u_digit( char32_t c, int radix ) – Returns the decimal digit value of the code point c in the specified radix.
• void u_toLower( char32_t c ) – Returns the lower case equivalent of code point c using non-Locale-based Unicode mapping.
• void u_toUpper( char32_t c ) – Returns the upper case equivalent of code point c using non-Locale-based Unicode mapping.
