I have this link:
<a href="data:application/pdf;base64,JVBERi0x...KJSVFT0YK">PDF</a>
In Safari on MacOsX, clicking the link instantly opens the PDF. In Firefox 3.6.2, it doesn't. When I choose Download, it saves it as "u7WYuJME.pdf(2).part", which is a valid PDF file. When I choose…

Is it possible to detect changes in the base64 encoding of an object to detect the degree of changes in the object.
Suppose I send a document attachment to several users and each makes changes to it and emails back to me, can I use the string distance between original base64 and the received base64s…

I'm currently implementing a client application that POST's a file over HTTP and have implemented base64 encoding on the file's data parameter.
However, it appears that when inspecting the traffic between a simple HTML page with a file upload form and the server that no Content-Transfer-Encoding…

I want to base64 encode data to put it in a URL and then decode it within my HttpHandler.
I have found that Base64 Encoding allows for a '/' character which will mess up my UriTemplate matching. Then I found that there is a concept of a "modified Base64 for URL" from wikipedia:
A modified Base64…

Consider the following problem:
A multi-line string $junk contains some lines which are encoded in UTF-8 and some in ISO-8859-1. I don't know a priori which lines are in which encoding, so heuristics will be needed.
I want to turn $junk into pure UTF-8 with proper re-encoding of the ISO-8859-1…

Excel seems to save CSV files in (what I think is) UTF-7, despite the fact that most information I have read suggest that in general, you should not UTF-7. Indeed, other applications (Text pad, which lets me choose) save things in UTF-8 (or Unicode etc, but UTF-7 is not even an option).
