 ### 3.4. Unicode编码 
 &emsp;&emsp;由于ANSI无法表达特定的编码，在跨地域时乱码的问题几乎无可避免，这就催生了Unicoed，这种一个联合编码集，意在使用一个字符集表达世界上所有语言所包含的所有书面符号(甚至是同一汉字的不同写法，如“户”和“戸”等)，且每一个符号都有自己唯一的编码，这样一来，乱码的问题就迎刃而解了。  
-&emsp;&emsp;Unicode码使用3字节的长度表达一个字符，最高字节为平面(Panel)索引，范围为0x00\~0x10(十进制17)，低两字节为字符码，表达范围为0\~65535。也就是说，Unicode编码的表达范围为0x000000\~0x10FFFF。

 &emsp;&emsp;为了兼容在VirtualSDK中运行、片上全字库运行和片上精简字库运行等多种情况，Demo程序中使用了DemoResource_UTF8.h、DemoResource_GB2312.h和DemoResource_ASCII.h三个文件作为显示用的资源文件，Demo程序中显示的文字均为同名不同内容的宏定义，在不同环境下根据不同的宏开关、引用不同的文件来实现切换不同显示内容的效果。    
-&emsp;&emsp;为了避免不同情况下的乱码，在VirtualSDK中运行时，使用的资源文件是DemoResource_UTF8.h，运行时通过iconv转换库将字符串转换为GB2312编码再进行解码和显示。 而由于在芯片上运行全字库时，由于没有足够的资源保存转码库的资源，所以使用DemoResource_GB2312.h文件，此文件本身就以GB2312形式保存无需转码，壳直接解码，而使用精简字库时，由于只有ASCII文字，所以使用DemoResource_ASCII.h文件，使界面显示英语，不使用中文字库。
