loading binary content?

[gnunicorn]

I am trying to sync a bunch of files from browserFS via the safenet library onto safenet but I get some problems with that in the browser and I am not sure, what is going wrong.

If I use the BrowserFS's fs.readFileSync() (which mimics the node js FS-module), it gives me a Buffer-Object, but passing that to safenet's nfs.updateFile doesn't work (it saves a json-to-string). While using fs.readFileSync(filename, 'utf8') appears to give me the string I can pass to updateFile, that fails on binary data (like PNG-files). Do you have any example of uploading a binary file via the safenet API? How are you doing it with buffers?
