encoding and transcoding

Tags: Ar SP strong data on problem BS as database Today, I encountered a problem. After several hours of finding an error, I was finally determined to be an Encoding Error. The original Encoding Error cannot be inserted into the database. The reason is that the data I collected is gb2312, and the database is utf8, so I have been wondering why the printed SQL statements are correct, but I cannot insert them

1. Overview 1.1. UseThe Cloud Vision Core Video transcoding system (" transcoding system ") can upload transcoded video files to the server via HTTP protocol.By default, an HTTP address is given to upload the file. In order to meet more complex application requirements, the transcoding system also supports more flexible upload methods, this document defines the

In development, we often need to change the N-file encoding, ICONV can only make changes to a single file, how to do? Let's write a shell script to solve this problem. Example one: Using shell script to implement bulk transcoding operation. #!/bin/sh # convertcodefilepath=$1 fromcode=$2 tocode=$3 for i ' {1..1} do [-f $convertCodeFilePath] if [ $? -eq 0] Then iconv-f $fromCode-T $toCode-C-O $conv

string.New String (Str.getbytes ("UTF-8"), "UTF-8"); // Normal New String (Str.getbytes ("UTF-8"), "GBK"); // not normal, Java built-in encoding->utf8 is converted to Java built -in encoding as GBK encodingTake a look at what the JDK documentation says. Public String (byte[] bytes, Charset Charset)Constructs a new String by decoding the specified array of bytes using the specified charset.So the ques

the word "medium" after using ISO8859-1 encoding and then combining it? In fact, the reason is very simple, because iso8859-1 encoded in the encoding table, there is no Chinese characters, of course, can not pass the "medium". GetBytes ("Iso8859-1"), to get the correct "medium" in the iso8859-1 of the encoded value, so again through the new String () to restore it is impossible to talk about.Therefore, whe

Php Chinese url transcoding 　　　 For URL encoding in PHP, urlencode () or rawurlencode () can be used. The difference between the two is that the former encodes spaces into '+ ', the latter encodes spaces into '% 20', but it should be noted that only part of the URL should be encoded, otherwise the colon and backslash in the URL will be escaped. The following is a detailed explanation:String url

control the policy of error handling, the default parameter is strict, which represents an exception thrown when an illegal character is encountered;If set to ignore, illegal characters are ignored;If set to replace, it will replace illegal characters;If set to Xmlcharrefreplace, the character reference of the XML is used.Python documentationDecode ([encoding[, errors]])Decodes the string using the codec registered for

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

In a project, encountered an interesting problem, after invoking a third-party interface callback local code, the encrypted request parameter decryption and transcoding, one of the decoding method is invalid, another decoding method valid, what solution? ：1. Encrypt a string when invoking a third-party interface:String str = "AKDFJLKSJFDLJSDLFSLFLD";(New Base64encoder ()). Encodebuffer (Str.getbytes ());2, synchronous callback local code when decrypti

This article provides a detailed analysis of PHP's automatic judgment of character sets and transcoding. For more information, see the principle. because gb2312/gbk is a two-byte Chinese character, these two bytes have a value range, while the Chinese character in UTF-8 is three bytes, and each byte also has a value range. The English language only occupies one byte (excluding the full width), regardless of the en
