Hi,
I had a UTF-8 BOM in my metadata.json and got really weird messages about "invalid JSON". Just wanted to say, in case others might have the same issue one day.

Ok, thanks. Yes, I think JSON is a bit strange about UTF8 - it might need the characters to be escaped.

What do you mean by 'BOM' though? I know it as 'Bill of Materials'

Byte Order Mask. A few bytes to tell the encoding of text files.

Ahh, right - just looked it up. Yes, Espruino (and the app loader) doesn't support a byte order mask in JSON.
