Bom--byte order mark, is the byte sequence mark
In the UCS code there is a character called ZERO WIDTH No-break Space, and its encoding is Feff. Fffe is not present in UCS, so it should not appear in the actual transmission. UCS specification recommended that we transfer the byte stream before the transmission of the character "ZERO WIDTH no-break space." This means that if the recipient receives the Feff, the byte stream is Big-endian, and if Fffe
The best method:
Let's talk about the basic things:
CodePage specifies the encoding used by IIS to read passed strings (such as form submission and address bar transfer ).
The cause of garbled characters is that the module encoding is different when the website is to be integrated.Like my blog, this problem occurs during integration, because the blog is Utf-
The GBK version of the common build program is the same as the UTF-8 version feature. It's just different coding methods.
GBK's text encoding is expressed in two-byte notation, that is, both Chinese and English characters use double-byte notation, except that the highest bits are set to 1 for distinguishing Chinese.
As for the
What is UTF8UTF8 is not a computer code, but a form of storage and transmission, as described above, each unicode/ucs character is stored in 2 or 4 bytes to see the following comparisons:Take "I am Chinese" as an exampleStore with ANSI: BytesStorage with UNICODE/UCS2: Bytes + 2 Bytes (header)Storage with UCS4: Bytes + 4 Bytes (header)Take the example of "I am Chinese"Store with ANSI: Ten BytesStorage with UNICODE/UCS2: Bytes + 2 Bytes (header)Storage with UCS4: Bytes + 4 Bytes (header)This shows
symbol, the first bit of the byte is set to 0, and the next 7 bits are the Unicode code for the symbol. So for the English alphabet, the UTF-8 encoding and ASCII code are the same. (The standard ASCII code is also called the base ASCII code, using a 7-bit binary number to represent all uppercase and lowercase letters, numbers 0 through 9, punctuation, and specia

If a website needs to be internationalized, it needs to convert the code from GB2312 to a UTF-8, there are many problems to note, if not completely converted, there will be a lot of coding problems! Next, I will share with you the php page through this article. mysql database is converted to UTF-8 garbled characters. e

UTF-32 stores each character in 4 bytes to ensure that the UCS is fully represented. However, the number of characters in the UCS does not need to be represented by 32 bits at all, UTF-32 greatly wasted space. In addition, because of the combination of characters, the fixed length is not as fast as expected to locate characters, anyway, is super bad.UTF-16 maps the UCS to a 16-long integer for data storage
In an xss problem encountered in this encoding problem, utf-7 and mutf-7 this encoding is used by mail, javamail should be supported, using utf-7 this is still relatively rare encoding can be used for some xss applications. Using Native jdk reports an error that does not sup

Transferred from: https://www.cnblogs.com/kclteam/p/5278926.htmlThe new project, presumably the situation is this: there may be many countries, different language users, the analogy of Chinese, traditional Chinese, Korean, Japanese and so on, the development of the choice of UTF-8 coding, development smooth, no problem. Yesterday did a CSV export function, the export of something completely chaotic:Set mb_c
Mysql in the utf8_general_ci is corresponding to the php document UTF-8 is the file format of UTF-8 without BOM encoding? Mysql in the utf8_general_ci is corresponding to the php document UTF-
As UTF-8 is a 8-bit encoding no BOM is required and Anyu+feff character in the decoded Unicode string (even if it ' s the F Irstcharacter) is treated as a ZERO WIDTH no-break SPACE.UTF-8 is encoded in bytes, its byte order is 様 in all systems, there is no byte order problem,
alphabet, the UTF-8 encoding and ASCII code are the same.2) for n-byte notation (n>1), the first n bits are set to 1, the n+1 bit is set to 0, and the first two bits of the subsequent bytes are set to 10. The rest of the bits are not mentioned, all of which are Unicode codes for this symbol.The following table summarizes the
Installing Eclipse or MyEclipse on a Chinese Windows operating system defaults to setting Eclipse's encoding to GBK, which is consistent with the operating system's default encoding. With this default setting, files added to eclipse are not automatically detected by Team Explorer, only in detected changes , and must be added to included changes by using the promote method (i) Figure one: Only new files can
In programming, these three character encoding formats are often converted to each other, so that many third-party libraries fail to call for unknown reasons, in fact, many are because third-party libraries support UTF-8 rather than Windows Default support of the UTF-16 caused.
