name="details" /><hr /><h2>Detailed Description</h2><p>The QChar class provides a 16-bit Unicode character.</p>
<p>In Qt, Unicode characters are 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 <tt>unsigned short</tt>.</p>
<p>QChar 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>
<p>The classification functions include functions like those in the standard C++ header <cctype> (formerly <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="qchar.html#isNull">isNull</a>() (returns true if the character is '\0'), <a href="qchar.html#isPrint">isPrint</a>() (true if the character is any sort of printable character, including whitespace), <a href="qchar.html#isPunct">isPunct</a>() (any sort of punctation), <a href="qchar.html#isMark">isMark</a>() (Unicode Mark), <a href="qchar.html#isLetter">isLetter</a>() (a letter), <a href="qchar.html#isNumber">isNumber</a>() (any sort of numeric character, not just 0-9), <a href="qchar.html#isLetterOrNumber">isLetterOrNumber</a>(), and <a href="qchar.html#isDigit">isDigit</a>() (decimal digits). All of these are wrappers around <a href="qchar.html#category">category</a>() which return the Unicode-defined category of each character.</p>
<p>QChar also provides <a href="qchar.html#direction">direction</a>(), which indicates the "natural" writing direction of this character. The <a href="qchar.html#joining">joining</a>() function indicates how the character joins with its neighbors (needed mostly for Arabic) and finally <a href="qchar.html#hasMirrored">hasMirrored</a>(), which indicates whether the character needs to be mirrored when it is printed in its "unnatural" writing direction.</p>
<p>Composed Unicode characters (like å) can be converted to decomposed Unicode ("a" followed by "ring above") by using <a href="qchar.html#decomposition">decomposition</a>().</p>
<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. operator==() and friends will do comparison based purely on the numeric Unicode value (code point) of the characters, and <a href="qchar.html#toUpper">toUpper</a>() and <a href="qchar.html#toLower">toLower</a>() will do case changes when the character has a well-defined uppercase/lowercase equivalent. For locale-dependent comparisons, use <a href="qstring.html#localeAwareCompare">QString.localeAwareCompare</a>().</p>
<p>The conversion functions include <a href="qchar.html#unicode">unicode</a>() (to a scalar), <a href="qchar.html#toLatin1">toLatin1</a>() (to scalar, but converts all non-Latin-1 characters to 0), <a href="qchar.html#row">row</a>() (gives the Unicode row), <a href="qchar.html#cell">cell</a>() (gives the Unicode cell), <a href="qchar.html#digitValue">digitValue</a>() (gives the integer value of any of the numerous digit characters), and a host of constructors.</p>
<p>QChar provides constructors and cast operators that make it easy to convert to and from traditional 8-bit <tt>char</tt>s. If you defined <tt>QT_NO_CAST_FROM_ASCII</tt> and <tt>QT_NO_CAST_TO_ASCII</tt>, as explained in the <a href="qstring.html">QString</a> documentation, you will need to explicitly call <a href="qchar.html#fromAscii">fromAscii</a>() or <a href="qchar.html#fromLatin1">fromLatin1</a>(), or use <a href="qlatin1char.html">QLatin1Char</a>, to construct a QChar from an 8-bit <tt>char</tt>, and you will need to call <a href="qchar.html#toAscii">toAscii</a>() or <a href="qchar.html#toLatin1">toLatin1</a>() to get the 8-bit value back.</p>
<p>See also <a href="qstring.html">QString</a>, <a href="unicode.html">Unicode</a>, and <a href="qlatin1char.html">QLatin1Char</a>.</p>
