JSON keys can only contain alpha characters

I was trying to insert a randomly generated ID from another system (e.g. 81ee344abf28aa3fbfd174eebf20686fc0164368) and ran into the following error:

2019/04/24 20:29:57 Error loading payload: Invalid key in data json: 81ee344abf28aa3fbfd174eebf20686fc0164368

Looking at the source code quick shows that account and transaction data object keys are limited to a small set of characters.

var validKey = regexp.MustCompile(`^[a-z_A-Z]+$`)

Is there any reason digits (0-9) can't be stored?

@adamdecaf To avoid any SQL injection with regards to the keys, the characters in the keys are whitelisted to what is known as valid. Initially we decided to have only alphabets and underscore. If necessary, we need to allow numbers too.

It would be nice. 0-9 doesn't expose queries to sql injection. I could transform the ID's to just alpha characters, but anyone trying to store UUID's (with -'s removed) would run into this problem.
