由于单一可执行文件支持所有语言，它需要一个编码系统，能够为每个字符提供一个唯一的编号，不论是何种平台、程序或语言。
Because the single executable supports all languages, it needs an encoding system to be able to provide a unique number for every character, no matter what the platform, program, or language.
在这些环境下，对于应用软件来说，要分布全球唯一的解决方案是 为每一种语言提供一个数据库，这样每一个数据库就可以支持一个单一的字符编码。
Under these circumstances, the only solution for the applications to go global is to provide a database for each language so that each database supports a single character encoding.
但是，当要处理的某一文档使用了不常用的编码(不能自动检测该编码，并且没有在文档中指定)时，则属性是唯一的解决方案。
But when that one document arrives that USES an uncommon encoding that cannot be auto-detected and is not specified in the document, properties are the only solution.
