## Detailed Description
这个类可以醃制。
该QChar类提供了一个16位的Unicode字符。
在Qt中, Unicode字符是没有任何标记或结构的16位实体。此类表示这样的实体。它是轻量级的,因此它可以随处使用。大多数编译器把它当作`unsigned short`。
QChar提供的测试/分类功能全套,转换和从其他格式,从组成到分解的Unicode转换,并试图比较和大小写转换,如果你问它。
分类功能包括像那些在标准C + +头\u003ccctype\u003e (原\u003cCTYPE.H\u003e )功能,但在全方位的Unicode字符操作。他们都返回True,如果该字符是某种类型的字符,否则返回假。这些分类功能[isNull](qchar.html#isNull)( ) (如果字符是'\ 0'返回True ) ,[isPrint](qchar.html#isPrint)( ) ( True如果字符是任何类型的可打印字符,包括空格的) ,[isPunct](qchar.html#isPunct)( ) (任何种类的点状的) ,[isMark](qchar.html#isMark)( ) ( Unicode的标志) ,[isLetter](qchar.html#isLetter)( ) (一个字母) ,[isNumber](qchar.html#isNumber)( ) (任何种类的数字字符,不只是0-9 ) ,[isLetterOrNumber](qchar.html#isLetterOrNumber)()和[isDigit](qchar.html#isDigit)( ) (小数位数) 。所有这些都是围绕包装[category](qchar.html#category)( ),它返回的Unicode定义的每个字符的类别。
QChar还提供[direction](qchar.html#direction)( ),表示这个人物的“自然”的写作方向。该[joining](qchar.html#joining)( )函数指示如何连接字符与邻国(主要是阿拉伯语需要) ,最后[hasMirrored](qchar.html#hasMirrored)( ),这表明该字符是否需要打印时在其“非自然”的写作方向进行镜像。
由Unicode字符(如A )可以通过使用被转换为Unicode的分解( “一”加“环以上” )[decomposition](qchar.html#decomposition)( ) 。
在Unicode中,比较未必能够和大小写转换是非常困难的最好的。 Unicode的,涵盖了“全”的世界,也包括世界上大部分的情况下和排序问题。运算符== ()和朋友会做的字符的数值Unicode值(代码点)完全基于比较和[toUpper](qchar.html#toUpper)()和[toLower](qchar.html#toLower)( )会做改变的情况下,当角色有一个明确定义的大写/小写形式。对于区域设置相关的比较,使用[QString.localeAwareCompare](qstring.html#localeAwareCompare)( ) 。
该转换功能包括[unicode](qchar.html#unicode)( )(一个标量) ,[toLatin1](qchar.html#toLatin1)( ) (标量,但将所有非Latin-1字符为0) ,[row](qchar.html#row)( ) (给出了统一行) ,[cell](qchar.html#cell)( ) (给出了Unicode的细胞) ,[digitValue](qchar.html#digitValue)( ) (给出任何的众多数字字符的整数值) ,以及一系列的构造函数。
QChar提供了构造函数和类型转换运算符,可以很容易转换,并从传统的8位`char`秒。如果你定义`QT_NO_CAST_FROM_ASCII`和`QT_NO_CAST_TO_ASCII`,如在解释[QString](qstring.html)文档,你将需要显式调用[fromAscii](qchar.html#fromAscii)()或[fromLatin1](qchar.html#fromLatin1)( ) ,或使用[QLatin1Char](qlatin1char.html),从8位构建QChar`char`,你将需要调用[toAscii](qchar.html#toAscii)()或[toLatin1](qchar.html#toLatin1)( )来得到8位的值返回。
