For some reasons, I need to detect whether the result is null or just a empty string , but most online tools don’t display the result object’s detail information. So I decide to write one. I may add “auto-highlighting matched words” function later, for now, it’s enough for me to play with.
When copying some of my old project files from Windows 7, the origin system text file encoding made some troubles for me. So in December, I wrote a small tool to help me out. But before days, the same problem came out again when the old mp3 ID3 tagged files met the iTunes. Therefore, I extended the tool to automatically convert the mp3 files to the specified encoding. I used the ID3iconv to help with the tag editing.
