Today engaged in sxna, encountered a difficult problem of encoding conversion, engaged in more than an hour, have a great deal of hard work, finally summed up the following Chinese characters into a variety of UTF-8 Unicode Ansi encoding program. I am afraid to enjoy it exclusively. I would like to dedicate it to programmers!

C language is efficient, flexible, and elegant. It is still a required basic course for various software design and development personnel. This book introduces the C language in a step-by-step manner, and explains th

"Share" Android Studio dedicated file Conversion tool: Save ANSI files in bulk as UTF-8 files without BOMWhen compiling Java files under Andoird Studio, there are often errors like the following:Error: (29, 43) downloading message: Ke policy home UTF-8 fermium Âμà switches Å è¡#̈亞 槧 hao 勫 瓧 quilting?Here, share a tool: ANSI files are saved in bulk as UTF-8 files without a BOM:Save the following code in No
When we write the program, the most used is the processing of the string, and the conversion between ANSI and Unicode often make us dizzy eye disorder.It should be said that Unicode is a good way to encode, in our program should try to use Unicode encoding, when we write programs, it is best to follow the following guidelines:Basic guidelines:1. Imagine a text string as a character array, not a char or byte array2. Start using common data types to rep

I did not notice that the differences in file encoding will cause so many problems. I have searched a lot of information before I started, and I have added many of my predecessors to my blog. I would like to pay tribute to them here!I will not talk about the principle of ANSI and Unicode encoding here. I will mainly talk about h
Recently written Network Data TransmissionProgramIt is a mess caused by various codes. The simple record here is as follows:
1. ASCII and ANSI Encoding
Charcter Code refers to the internal code used to represent characters. Readers must use the internal code when entering and storing documents. The internal code is dividedA. single-byte internal code-single-byte character sets (sbcs), which can be encoded with 256 characters.B. Double Byte interna
Following the story of the previous episode, the multi-character set (ANSI) and Unicode and string processing methodsWe have some special requirements:
Sometimes our string is of the Multi-character type, but we need to use the wide character type; sometimes, the opposite is true.
Windows provides such a function to solve this problem:
1. multibytetowidechar
Function:This function maps a string to a unicode string. The string mapped by this functi
Conversions between ANSI, Unicode, and wide characters
Method One, use MultiByteToWideChar to convert ANSI characters to Unicode characters, and use WideCharToMultiByte to convert Unicode characters to ANSI characters.
Method Two, use "_t" to convert ANSI to a "generic" type string, convert
This article describes a Python-based batch conversion method that implements Java source code from ANSI to UTF-8. Share to everyone for your reference. Specific as follows:
Like with eclipse of the great gods, may accidentally code becomes ANSI code, need to convert to Utf-8, a file of a file in the Notepad2 or notepad++ inside conversion? No, there are batch conversion programs, Python implementation, ne
error messages.Therefore, it is better to define a macro to avoid making mistakes:#define Chmalloc (ncharacters) (tchar*) malloc (ncharacters * sizeof (TCHAR))7. Avoid using the functions of the printf system, especially if you do not use the%s and%s field types for the conversion between ANSI and string.The correct approach is to use the MultiByteToWideChar and WideCharToMultiByte functions.8. The UNICODE and _unicode symbols are either specified, o

Similarly, open with text mode, save with binary, and then open with a text program, there is less than A/R, as follows:
And for such a malformed thing, Windows itself is not aware of Notepad:
