Background
Developers who have developed Windows Mobile and Windows Embedded CE, especially Native C ++, have encountered conversion of ANSI and Unicode character sets more or less. This article attempts to understand the character set issues developed by Windows Mobile and Windows Embedded CE. In fact, this question is a bit ambitious and aggressive.
Introduction
This article attempts to clarify
Introduction"Character and encoding" is a frequently discussed topic. Even so, garbled characters often plague everyone. Although we have many ways to eliminate garbled characters, we do not necessarily understand the internal principles of these methods. Some causes of garbled code are actually caused by problems with the underlying code itself. Therefore, not only do beginners feel fuzzy about character encoding, but some underlying developers also lack an accurate understanding of character e

Void description
Void is "no type", void * is "no type Pointer", can point to any data type.
Void pointer usage Specification① The Void pointer can point to any type of data, that is, the void pointer can be assigned a value to any type of data. For example:Int * pint;Void * pvoid;Pvoid = pint;/* but cannot pint = pvoid ;*/If you want to assign pvoid to another type pointer, You need to force type conversion, for example, pint = (int *) pvoid;② In ansi

VC++6.0Unicode programming is supported, but the default value is ANSI. developers can easily write UNICODE-Supported Applications by slightly changing the coding habits.
UseVC++6.0Unicode programming mainly involves the following tasks:
1. Add UNICODE and _ UNICODE preprocessing options for the project.
Specific steps: open [project]-> [settings…] In the "pre-processing program definition" in the C/C ++ label dialog box, remove _ MBCS and add _ UNICO
1. Standard C languageThe C language was born in the 1970s, older than ourselves, and produced many standards, but various compilers support different standards.ANSI C is the most widely used standard and is also the first formal standard, known as "Standard C language". ANSI C was released in 1980 by the U.S. National Bureau of Standards (American Nation Standards Institute, abbreviation ANSI), the various
