This class represents such an entity. It is lightweight, so it can be used everywhere. Most compilers treat it like a "short int".

They all return TRUE if the character is a certain type of character; otherwise they return FALSE. These classification functions are isNull() (returns TRUE if the character is U+0000), isPrint() (TRUE if the character is any sort of printable character, including whitespace), isPunct() (any sort of punctation), isMark() (Unicode Mark), isLetter (a letter), isNumber() (any sort of numeric character), isLetterOrNumber(), and isDigit() (decimal digits). All of these are wrappers around category() which return the Unicode-defined category of each character. .PP -QChar further provides direction(), which indicates the "natural" writing direction of this character. The joining() function indicates how the character joins with its neighbors (needed mostly for Arabic) and finally mirrored(), which indicates whether the character needs to be mirrored when it is printed in its" unnatural" writing direction. +TQChar further provides direction(), which indicates the "natural" writing direction of this character. The joining() function indicates how the character joins with its neighbors (needed mostly for Arabic) and finally mirrored(), which indicates whether the character needs to be mirrored when it is printed in its" unnatural" writing direction. .PP Composed Unicode characters (like å) can be converted to decomposed Unicode ("a" followed by "ring above") by using decomposition(). .PP -In Unicode, comparison is not necessarily possible and case conversion is very difficult at best. Unicode, covering the" entire" world, also includes most of the world's case and sorting problems. TQt tries, but not very hard: operator==() and friends will do comparison based purely on the numeric Unicode value (code point) of the characters, and upper() and lower() will do case changes when the character has a well-defined upper/lower-case equivalent. There is no provision for locale-dependent case folding rules or comparison; these functions are meant to be fast so they can be used unambiguously in data structures. (See QString::localeAwareCompare() though.) +In Unicode, comparison is not necessarily possible and case conversion is very difficult at best.
