encoding and transcoding

In Linux iconv is a command to transcode, when the data file import into the database is often encountered, the character encoding format of the data file and the character encoding format required in the database is inconsistent, then will often use the Iconv this commandIconv Common parameters-F Original Code-T target encoding-C ignores characters that cannot b

Sometimes I also think that I add Tomcat Chinese transcoding is OK, and later found that I have been suffering from a pain... The JSP page contains Chinese characters, but it is okay when you look at the JSP page. It does not mean that the jsp url is passed as a value, and the background accepts Chinese encoding, at least what I encounter is garbled characters ??????? Solution JSP page Needless to say:

We introduced in the previous article The Json_encode () function in PHP and how to use it, when we work will use Json_encode to deal with Chinese, Chinese will be encoded, become unreadable, similar to "\u***" format, if you want Chinese characters do not transcode , here are three ways to solve the problem of Json_encode Chinese Unicode transcoding! 1. Upgrade PHP, in PHP5.4, the problem is finally resolved, JSON added an option: Json_unescaped_unic

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

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

When 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 1. Upgrade PHP, in PHP5.4, the problem is finally resolved, JSON added an option: Json_unescaped_unicode, so the name Incredibles, that is, JSON do not encode UNICODE. 2. UrlEncode the Chinese characters first and then use the Json_encode,json_encode again after using the UrlDecode to decode, so that the en

I added a coded sentence to the JSP file: Then, in the program, make a transcoding of the Chinese character: In the database: Name=request.getparameter ("name"). Trim (); Name=new String (name2.getbytes ("GB2312"), "iso-8859-1"); To remove from the database: Listname=new String (rs.getstring ("name"). GetBytes ("Iso-8859-1"), "GB2312"); and database, Tomcat is using the default encoding.

The principle is very simple, because the GB2312/GBK is Chinese two bytes, these two bytes is a range of values, and utf-8 Chinese characters are three bytes, also have a range of values for each byte. The English language is less than 128, regardless of the encoding, and occupies only one byte (except all corners).If it is a file-form code check, you can also check Utf-8 's BOM information directly. To say, directly on the function, this function is

Before using the UC cloud transcoding, you must download the video files offline to the UC cloud disk before you can carry out the cloud transcoding. 1. Open UC Browser, main menu → download/application →UC network disk, offline download is located in the upper right corner. 2. Click to enter offline download, click "New Offline Task", enter HTTP, Thunder, FTP, Donkey ed2k and other resources

Between the browser and the server, the transfer of data, will involve transcoding problems, this article describes the specific situation.One, typeThere are three types of transmission that will have transcoding problems (WebSocket does not have this problem), including cookies and get,post.A, cookiesSomething in the client cookie will not be transcoded, but once transferred to the server, it will be autom

Python has both Str object and Unicode object two strings that can hold the byte encoding of the characters, but they are different types, which is important and why there are encode and decode.The significance of encode and decode in Pyhton can be expressed asEncodeUnicode-------------------------> strUnicode DecodeSeveral common methods:Str_string.decode (' codec ') is to convert str_string to unicode_string, codec is the

For this (class) issue:(1) The problem occurs when the unicodeencodeerror–> description is Unicode encoding;(2) ' GBK ' codec can ' t encode character–> description is an issue that occurs when encoding Unicode characters as GBK;At this point, it is often most likely that the character of the Unicode type itself contains some characters that cannot be converted to GBK encoding.The solution is: Scen

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
