import ‘dart:convert’; String foo = ‘Hello world’; List<int> bytes = utf8.encode(foo); print(bytes); Output: [72, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100] Also, if you want to convert back: String bar = utf8.decode(bytes);
I have a colleague who worked on ZXing (“Zebra Crossing”). That’s got a fair variety of platform support.
The problem was caused by: Get-Content without -raw splits the file into an array of lines thus destroying the code Text.Encoding interprets the binary code as text thus destroying the code Out-File is for text data, not binary code The correct approach is to use IO.File ReadAllBytes: $base64string = [Convert]::ToBase64String([IO.File]::ReadAllBytes($FileName)) and WriteAllBytes to decode: [IO.File]::WriteAllBytes($FileName, … Read more
For when automagicalism doesn’t work, and you’re definitely using Excel, use this as the field content. =HYPERLINK(“http://stackoverflow.com”)
… There’s a reason they’re called “encodings” … A little preamble: think of unicode as the norm, or the ideal state. Unicode is just a table of characters. №65 is latin capital A. №937 is greek capital omega. Just that. In order for a computer to store and-or manipulate Unicode, it has to encode it … Read more
Assuming the image data is already in the format you want, you don’t need ImageIO at all – you just need to write the data to the file: // Note preferred way of declaring an array variable byte[] data = Base64.decodeBase64(crntImage); try (OutputStream stream = new FileOutputStream(“c:/decode/abc.bmp”)) { stream.write(data); } (I’m assuming you’re using Java … Read more
Try below code line instead of last two lines. Hope it helps: line=line.decode(‘utf-8′,’ignore’).encode(“utf-8”)
