I’ve run into a problem with the base64 encoding.

/usr/bin/base64 encodes this file differently from Emacs:

librsvg doesn’t like the way Emacs encodes the file, but is fine with
the system base64.

I think the problem is the GBP £ symbol on line 39.

Do I need to do something special, like set up character encodings?
