I need to make a detour for a few moments, and discuss how to handle strings in COM code. If you are familiar with how Unicode and ANSI strings work, and know how to convert between the two, then you can skip this section. Otherwise, read on. Wheneve…

众所周知,一个文字从输入到显示到存储是有一个固定过程的,其过程为:输入码(根据输入法不同而不同)→机内码(根据语言环境不同而不同,不同的系统语言编码也不一样)→字型码(根据不同的字体而不同)→存储码(根据保存的编码类型不同而不同).不同的存储码之间又有什么异同呢? 一.ASCII系列编码 首先来说明ASCII码(American Standard Code for Information Interchange,美国标准信息交换码),这个编码的时代就久远了,是由美国国家标准局(ANSI)制定,目…
