Today, using Unicode as a string is a common sense, but it's still a headache for some programming languages with a long history. Without the support of a third-party library, C + + does not actually support Unicode effectively, even if it is UTF8. (
1. How do I get the number of characters in a string that contains both Single-byte characters and double-byte characters?
You can call the runtime library of Microsoft Visual C + + to include function _mbslen to manipulate multibyte (both

Unicode is encoded like "u+4e25" or "\u4e25", in many cases 4 hexadecimal digits, sometimes more than one.Unicode encoding system can be divided into two levels of encoding and implementation:Encoding method: "Strict" Unicode is 4E25;Realization way:
In r13a, Erlang has added support for Unicode. The data types covered in this article include: list, binary, modules involved Stdlib/unicode, Stdlib/io, Kernel/file. Binary The binary type attribute increases the UTF-related Type:utf8, UTF16, UTF32,

The coding aspect has always been not very high, so it is not known about Unicode and UTF-8.
Recently accidentally turned to a UTF-8 article, feel the explanation of the very complex, so just thought to write a simple and understandable.

Unicode is commonly used in the UCS-2, it uses two bytes to encode a character, such as the Chinese character "warp" encoding is 0X7ECF, 0X7ECF converted to decimal is 32463,ucs-2 with two bytes to encode characters, 2 16 is equal to 65536, so

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
