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.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

Just like Github, a blank line must precede a code block.
