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

Data is transferred at business time and needs to be transcoded, from UTF-8 to GBK. PHP functions are relatively mentally retarded, leading to a large amount of data conversion failures. Is there a better transcoding method that can automatically ignore the codes in the content that cannot be converted successfully, so don't lose data? Data is transferred at business time and needs to be transcoded, from UTF-8 to GBK. PHP functions are relatively ment

This article mainly introduces the unicode transcoding method in Javascript. If you need unicode, you can refer to it and sometimes you have to transcode it. We have to manually transcode it. I saw a unitcode transcoding method on the internet yesterday, which is very easy to use! Let me share it with you. JavaScript script UniCode transcoding functions:

Using a transcoding service such as avthumbmp3 and saveas, will the uploaded source files be retained? For example, if I have uploaded the audio file xxx.m4a and the fixed conversion code is xxx.mp3, will xxx. m4a be retained? Using a transcoding service like avthumb/mp3 | saveas/, will the uploaded source files be retained? For example, if I upload a audio file of xxx. m4a and its conversion code is xxx.m
