What encoding is this?

Below is a short sample of a encoded message, does anybody recognize what encoding this is? It is not base64.

It is not Base64!
It contains invalid characters to be Base64
Oh?

Which ones?

Wikipedia's article on Base64 states:
...There are other variants that use '_-' or '._' when the Base64 variant string must be used within valid identifiers for programs....
so in this situation _ and - may very well be appropriate characters for the data. Judging by the character set, I am strongly leaning towards base 64 as the first stage of encoding.

What are you talking about?
See for yourself, the decoded string using Base64 doesn't come close to anywhere!

If your so sure it's Base64 then go ahead and decode it! There are many online decoders, but the decoded string looks worse than the original string!

Unless you take a second to consider that the result might very well be binary data, in which case is is perfectly reasonable to base-64 encode it to incorporate in an error message (for logging purposes, in a database perhaps).

It's probably just a chunk out of the middle of a video stream or something.

I would have to agree with this. I've had problems viewing links to .mov or ogg encoded video streams and if I do not have the proper filter installed in firefox all I get is streams of jibberish that would decode to video and audio had I installed the proper plugins.

It's definitely not.
On this error page they asked me to report this to then and give them this block of code.

So it's some real stuff, not an accidental chunk...

Could be a portion of a movie file that caused the error. The YouTube staff might want to analyze it so see where the exception got thrown.

Why they need you to send them the data manually instead of using an automated logger, though.... Dunno about that one.

It does seem a little odd, given that they had to transmit it to you in the first place.

1. How do I determine which encoding a xmldocument or xmlreader uses when opening a document? I'm not just talking about the <?xml encoding="utf-8"?attribute, but the actual encoding of the characters in the underlying stream. 2. How do I make sure that the encoding of my created xmldocument or xmlwriter is in utf-8? Thanks! /mortb
