transcoding service

In Python, you can invoke the decode and encode methods on a string to implement transcoding. For example, to convert a string object s from GBK inside code to UTF-8, you can do the followingS.decode (' GBK '). Encode (' utf-8′)However, in real-world development, I found that this approach often occurs abnormally:Unicodedecodeerror: ' GBK ' codec can ' t decode bytes in position 30664-30665:illegal multibyte sequenceThis is because illegal characters

This article provides a detailed analysis of PHP's automatic character set judgment and transcoding. For more information, see This article provides a detailed analysis of PHP's automatic character set judgment and transcoding. For more information, see The principle is very simple. VM, because gb2312/gbk is a Chinese byte, the two bytes have a value range, while UTF-8 contains three Chinese characters

Address: Php solve json_encode Chinese Unicode transcoding problemWhen using PHP json_encode to handle Chinese, Chinese will be encoded, become unreadable, similar to the "\u***" format, if you want Chinese characters do not transcode,Here are three ways to findJson_unescaped_unicode, hence the name Incredibles, that is, JSON does not encode UNICODE.2. UrlEncode the Chinese characters first and then use the Json_encode,json_encode again after using th

I recently in doing oaf two times development, in looking at other people write code, found that there are always similar statements: "\U65E0\U6548\U7684GP\U9879\U76EE\U7F16\U53F7", these statements are actually used Java_ The tools in Home are Native2ascii.exe transcoded. Oracle does not recommend this when displaying a message notification, and is usually a message that is assigned under the responsibility of the app developer. Let me show you how to use the Native2ascii.exe tool to transcode

Recently playing some reptiles, Python Chinese transcoding just contact is a troublesome thing (the principle of conversion omitted)Generally there are encode (' GBK '), Edcode (' UTF8 '), decode (' GBK '), decode (' UTF8 ') can solve a very large problemBut today I met the ' \\u6210\\u529f ' format, and the kick on it.Through the almighty degree Niang, found the first post, breathtakingHttp://bbs.chinaunix.net/thread-3674073-1-1.htmlThe code is as fo

There is a page, through the window.open to open another page, to open the address inside there is a parameter title, the value is Chinese, is through the function of PHP urlencode conversion, but jump past the title of the first Chinese characters displayed normal, is the Chinese character, The second character is automatically encoded, the address bar is no longer displayed in Chinese characters, in order to solve this problem, I put the value of Chinese characters with JS Encoderuicomponent

PHP automatically recognizes character sets and completes transcoding because it uses UTF-8 encoding. However, if the other party's blog uses gb2312 encoding, garbled characters will appear after the POST (unless the encoding is converted before the POST ). It is necessary to perform an encoding check and conversion on your own without ensuring that the other party must use UTF-8 encoding. I wrote a function to complete this operation. The principle i

Are you still using iconv for php transcoding functions ?. When using PHP to process strings, we often encounter character encoding conversion problems. Have you ever encountered iconv conversion failure? When I found the problem, I searched the internet and found that iconv was originally using PHP to process strings. we often encountered character encoding conversion problems. Have you ever encountered iconv conversion failure? When I found the pro

This article describes how to solve the problem of truncation characters during iconv function transcoding in PHP. the solution provided in this article is to use mb_convert_encoding instead of iconv, if you need iconv, refer to iconv conversion encoding. However, the iconv is not fully displayed during Chinese transcoding. The code is as follows: Iconv ("UTF-8", "GB2312 // IGNORE", $ data); with // IG

To meet certain special needs, characters must be transcoded according to rules to facilitate transmission, presentation, and other operations. Let's take a look at the following transcoding to find out its usefulness. 1. String transcoding completes Conversion Based on the original encoding format and the target encoding format. However, garbled characters may occur. The previous chapter has already been i
