Native2ascii is a transcoding tool provided by the Sun Java SDK to convert other text class files (such as *.txt, *.ini, *.properties, *.java, and so on) to Unicode encoding.1. How do I get native2ascii.exe?After installing the JDK, if you are installing on Windows, there will be a bin directory under the JDK installation directory, which will have the Native2ascii.exe tools we need.2. Native2ascii.exe How to use: Java

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

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 $convertCodeFilePath $convertCodeFilePath if [$-ne

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.

Method One: If we install "Storm Code 1.0", we just drag the file to the transfer code directly into the storm.Method Two:1. This is also the opening of the storm after we click "Add Files" and will pop up to select the computer to transfer the code of the video file 3. Select the file that requires transcoding (you can use CTRL or SHIFT to select multiple), and then click on "Open" which is very simple to choose a number of files. 3. OK to add th

compatible gb2312 , but not all can turn back to each other, it is best to use iso-8850-1 as the intermediate transcoding character set, because all the character sets are iso-8859-1 compatible, whether GBK or gb2312,utf-8, can be perfectly converted back. Say so much, perhaps everybody still a little confused, this application is in where. I give an example, you know, often some people do web crawler, download the Web page, but, a variety of Web pa

[This article is a complex topic of FFMPEG. It will be quite cool to write] [Different transcoding environments may have different code flows] First popularized: Timestamp, DTS (Decoding time stamp), PTS (presention time stamp), CTS (current time stamp ). The timestamp in ffmepg is in microseconds and is related to the timebase variable. It is used as the time benchmark granularity of DTs and PTS, and the value will be large. Among them, the av_resc

The difference between libiconv and glibc is the same article. I prefer iconv function for transcoding, while mb_convert_encoding function for backup. The iconv information in the same article: phpinfo is as follows: Iconv implementation "libiconv" In this way, the iconv transcoding content is complete. The phpinfo information of another machine is as follows: Iconv implementation glibc In this way, the ico

Complete pasted on http://community.csdn.net/Expert/TopicView3.asp? Id = 4563329 Here I will focus on my points: The encoding problem should not be solved in this way. The landlord's starting point is good, but there is a problem with the idea of solving the problem. At best, this is a patch under certain conditions. I am talking about the "Train of Thought problem". Does the landlord ever think that encoding is actually an underlying (relative to the application you developed) facility. You onl

last recorded video is in one file, or you will generate a separate file for each recording. After using these two commands, the transcoding will also be performed at intervals of time, but the final output (overwrite) is in the same file. The advantage is that it can be almost "real-time" transcoding, the disadvantage is to repeatedly call FFmpeg, occupy the system resources. 3, it should be noted that th
