Try this piece of code $pdf_base64 = “base64pdf.txt”; //Get File content from txt file $pdf_base64_handler = fopen($pdf_base64,’r’); $pdf_content = fread ($pdf_base64_handler,filesize($pdf_base64)); fclose ($pdf_base64_handler); //Decode pdf content $pdf_decoded = base64_decode ($pdf_content); //Write data back to pdf file $pdf = fopen (‘test.pdf’,’w’); fwrite ($pdf,$pdf_decoded); //close output file fclose ($pdf); echo ‘Done’;
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
You have Integer#to_s(base) and String#to_i(base) available to you. Integer#to_s(base) converts a decimal number to a string representing the number in the base specified: 9.to_s(2) #=> “1001” while the reverse is obtained with String#to_i(base): “1001”.to_i(2) #=> 9

Edit: Since I wrote this answer Base64.strict_encode64() was added, which does not add newlines. The docs are somewhat confusing, the b64encode method is supposed to add a newline for every 60th character, and the example for the encode64 method is actually using the b64encode method. It seems the pack(“m”) method for the Array class used … Read more
Checkout the Ruby CGI class. There are methods to encode and decode HTML as well as URLs. CGI::escapeHTML(‘Usage: foo “bar” <baz>’) # => “Usage: foo "bar" <baz>”
The reason why unserialize() fails with: $ser=”a:2:{i:0;s:5:”héllö”;i:1;s:5:”wörld”;}”; Is because the length for héllö and wörld are wrong, since PHP doesn’t correctly handle multi-byte strings natively: echo strlen(‘héllö’); // 7 echo strlen(‘wörld’); // 6 However if you try to unserialize() the following correct string: $ser=”a:2:{i:0;s:7:”héllö”;i:1;s:6:”wörld”;}”; echo ‘<pre>’; print_r(unserialize($ser)); echo ‘</pre>’; It works: Array ( [0] => … Read more
Use encodeURIComponent() in JS and in PHP you should receive the correct values. Note: When you access $_GET, $_POST or $_REQUEST in PHP, you are retrieving values that have already been decoded. Example: In your JS: // url encode your string var string = encodeURIComponent(‘+’); // “%2B” // send it to your server window.location = … Read more
First, convert the base 64 string to an Image, then use the Image.Save method. To convert from base 64 string to Image: public Image Base64ToImage(string base64String) { // Convert base 64 string to byte[] byte[] imageBytes = Convert.FromBase64String(base64String); // Convert byte[] to Image using (var ms = new MemoryStream(imageBytes, 0, imageBytes.Length)) { Image image = … Read more
Found a solution: In my unicode I replaced ‘U+‘ by ‘0x‘ Example: replace ‘U+1F60A‘ by ‘0x1F60A‘ This way I got an ‘int’ like int unicode = 0x1F60A; Which can be used with public String getEmojiByUnicode(int unicode){ return new String(Character.toChars(unicode)); } So Textview displays 😊 without Drawable Try it with http://apps.timwhitlock.info/emoji/tables/unicode
