Linux下的中文字体安装和使用

fedora对中文的支持很好，默认情况下安装了两种中文字体，但是系统自带字体的字库很小，对于一些不常用的字无法显示。还有就是部分用户会跨平台办公，也就为了兼容windows 环境，必须要用到windows 的字体，如宋体、仿宋、楷体、黑体等，再有就是为了美化linux 桌面环境安装美化字体。
1 安装中文字体
安装字体非常简单，只要把中文字体复制到字体目录就可以了，绝对路径如下，注意大小写：/usr/share/fonts/chinese/TrueType/
如果大家安装的是双系统，也可以不用把windows下的字体原文件复制到linux 中文字体目录，可以建立每个字体文件的链接（如何用鼠标拖动创建文件链接前面介绍了，比较简单）就可以，如图1 所示，图标右边带一个弯曲箭头符号的就是一个链接文件，大家可能看到的图标也许和我不同，因为我使用了fedora 自带的“薄雾”主题而不是默认的主题，为了节省系统资源加快运行速度。
xp 下主要字体为：宋体simsun.ttc、黑体simhei.ttc、仿宋simfang.ttf、楷体simkai.ttf、隶书simli.ttf、幼圆simyou.ttf,另外推荐大家安装微软雅黑字体，以便用来美化fedora 的显示，图1 就是使用雅黑字体的效果，挺养眼的。
Parameters
- format
- C string that contains one or more of the following items:
- Whitespace character: the function will read and ignore any whitespace characters (this includes blank spaces and the newline and tab characters) which are encountered before the next non-whitespace character. This includes any quantity of whitespace characters, or none.
- Non-whitespace character, except percentage signs (%): Any character that is not either a whitespace character (blank, newline or tab) or part of a format specifier (which begin with a % character) causes the function to read the next character from stdin, compare it to this non-whitespace character and if it matches, it is discarded and the function continues with the next character of format. If the character does not match, the function fails, returning and leaving subsequent characters of stdin unread.
- Format specifiers: A sequence formed by an initial percentage sign (%) indicates a format specifier, which is used to specify the type and format of the data to be retrieved from stdin and stored in the locations pointed by the additional arguments. A format specifier follows this prototype:
%[*][width][modifiers]type
where:
* An optional starting asterisk indicates that the data is to be retrieved from stdin but ignored, i.e. it is not stored in the corresponding argument. width Specifies the maximum number of characters to be read in the current reading operation modifiers Specifies a size different from int (in the case of d, i and n), unsigned int (in the case of o, u and x) or float (in the case of e, f and g) for the data pointed by the corresponding additional argument:
h : short int (for d, i and n), or unsigned short int (for o, u and x)
l : long int (for d, i and n), or unsigned long int (for o, u and x), or double (for e, f and g)
L : long double (for e, f and g)type A character specifying the type of data to be read and how it is expected to be read. See next table.
scanf type specifiers:type Qualifying Input Type of argument c Single character: Reads the next character. If a width different from 1 is specified, the function reads width characters and stores them in the successive locations of the array passed as argument. No null character is appended at the end. char * d Decimal integer: Number optionally preceded with a + or - sign. int * e,E,f,g,G Floating point: Decimal number containing a decimal point, optionally preceded by a + or - sign and optionally folowed by the e or E character and a decimal number. Two examples of valid entries are -732.103 and 7.12e4 float * o Octal integer. int * s String of characters. This will read subsequent characters until a whitespace is found (whitespace characters are considered to be blank, newline and tab). char * u Unsigned decimal integer. unsigned int * x,X Hexadecimal integer. int *
- additional arguments
- The function expects a sequence of references as additional arguments, each one pointing to an object of the type specified by their corresponding %-tag within the format string, in the same order.
For each format specifier in the format string that retrieves data, an additional argument should be specified.
These arguments are expected to be references (pointers): if you want to store the result of a fscanf operation on a regular variable you should precede its identifier with the reference operator, i.e. an ampersand sign (&), like in:
int n;
scanf ("%d",&n);
Return Value
On success, the function returns the number of items succesfully read. This count can match the expected number of readings or fewer, even zero, if a matching failure happens.In the case of an input failure before any data could be successfully read, EOF is returned.另存为草稿

This example demonstrates some of the types that can be read with scanf:
Enter your family name: Soulie
Enter your age: 29
Mr. Soulie , 29 years old.
Enter a hexadecimal number: ff
You have entered 0xff (255).
