The TQChar class provides a lightweight Unicode character.
< p >
< p > Unicode characters are (so far) 16-bit entities without any markup
or structure. This class represents such an entity. It is
lightweight, so it can be used everywhere. Most compilers treat it
like a "short int". (In a few years it may be necessary to make
TQChar 32-bit when more than 65536 Unicode code points have been
defined and come into use.)
< p > TQChar provides a full complement of testing/classification
functions, converting to and from other formats, converting from
composed to decomposed Unicode, and trying to compare and
case-convert if you ask it to.
< p > The classification functions include functions like those in
ctype.h, but operating on the full range of Unicode characters.
They all return TRUE if the character is a certain type of
character; otherwise they return FALSE. These classification
functions are < a href = "#isNull" > isNull< / a > () (returns TRUE if the character is U+0000),
< a href = "#isPrint" > isPrint< / a > () (TRUE if the character is any sort of printable
character, including whitespace), < a href = "#isPunct" > isPunct< / a > () (any sort of
punctation), < a href = "#isMark" > isMark< / a > () (Unicode Mark), isLetter (a letter),
< a href = "#isNumber" > isNumber< / a > () (any sort of numeric character), < a href = "#isLetterOrNumber" > isLetterOrNumber< / a > (),
and < a href = "#isDigit" > isDigit< / a > () (decimal digits). All of these are wrappers around
< a href = "#category" > category< / a > () which return the Unicode-defined category of each
character.
< p > TQChar further provides < a href = "#direction" > direction< / a > (), which indicates the "natural"
writing direction of this character. The < a href = "#joining" > joining< / a > () function
indicates how the character joins with its neighbors (needed
mostly for Arabic) and finally < a href = "#mirrored" > mirrored< / a > (), which indicates whether
the character needs to be mirrored when it is printed in its
"unnatural" writing direction.
< p > Composed Unicode characters (like å ) can be converted to
decomposed Unicode ("a" followed by "ring above") by using
< a href = "#decomposition" > decomposition< / a > ().
< p > 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: < a href = "#operator-eq-eq" > operator==< / a > () and friends
will do comparison based purely on the numeric Unicode value (code
point) of the characters, and < a href = "#upper" > upper< / a > () and < a href = "#lower" > lower< / a > () 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
< a href = "tqstring.html#localeAwareCompare" > TQString::localeAwareCompare< / a > () though.)
< p > The conversion functions include < a href = "#unicode" > unicode< / a > () (to a scalar), < a href = "#latin1" > latin1< / a > ()
(to scalar, but converts all non-Latin-1 characters to 0), < a href = "#row" > row< / a > ()
(gives the Unicode row), < a href = "#cell" > cell< / a > () (gives the Unicode cell),
< a href = "#digitValue" > digitValue< / a > () (gives the integer value of any of the numerous digit
characters), and a host of constructors.

< p > Returns the Latin-1 value of this character, or 0 if it
cannot be represented in Latin-1.
< h3 class = fn > < a href = "qchar.html" > TQChar< / a > < a name = "lower" > < / a > TQChar::lower () const
< / h3 >
Returns the lowercase equivalent if the character is uppercase;
otherwise returns the character itself.
< h3 class = fn > bool < a name = "mirrored" > < / a > TQChar::mirrored () const
< / h3 >
Returns TRUE if the character is a mirrored character (one that
should be reversed if the text direction is reversed); otherwise
returns FALSE.
< h3 class = fn > < a href = "qchar.html" > TQChar< / a > < a name = "mirroredChar" > < / a > TQChar::mirroredChar () const
< / h3 >
Returns the mirrored character if this character is a mirrored
character, otherwise returns the character itself.

< / h3 >
< p > < b > This function is obsolete.< / b > It is provided to keep old source working. We strongly advise against using it in new code.
< p > Returns TRUE if this character is in network byte order (MSB
first); otherwise returns FALSE. This is platform dependent.
< h3 class = fn > < a name = "operator-char" > < / a > TQChar::operator char () const
< / h3 >
< p > Returns the Latin-1 character equivalent to the TQChar, or 0. This
is mainly useful for non-internationalized software.
< p > < p > See also < a href = "#unicode" > unicode< / a > ().
< h3 class = fn > uchar < a name = "row" > < / a > TQChar::row () const
< / h3 >
< p > Returns the row (most significant byte) of the Unicode character.
< h3 class = fn > ushort < a name = "unicode" > < / a > TQChar::unicode () const
< / h3 >
< p > Returns the numeric Unicode value equal to the TQChar. Normally,
you should use TQChar objects as they are equivalent, but for some
low-level tasks (e.g. indexing into an array of Unicode
information), this function is useful.
< h3 class = fn > ushort & < a name = "unicode-2" > < / a > TQChar::unicode ()
< / h3 >
< p > This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
< p > Returns a reference to the numeric Unicode value equal to the
TQChar.
< h3 class = fn > < a href = "qchar.html" > TQChar< / a > < a name = "upper" > < / a > TQChar::upper () const
< / h3 >
Returns the uppercase equivalent if the character is lowercase;
otherwise returns the character itself.
