What characters are allowed in a Firestore path?

[Bartholomew Furrow]

I've Googled all over, and haven't found this. Is there any character that can't appear in a segment of a Firestore path other than / ? This node_js API line from path.js seems to confirm that any character is valid, but I'd like to make sure before using email addresses (with / characters escaped) as keys.

const RESOURCE_PATH_RE = /^projects\/([^/]*)\/databases\/([^/]*)(?:\/documents\/)?(.*)$/;

Thanks,

Bartholomew

It's in the Firestore documentation about Quotas and Limits - Standard limits, scroll to the lower part of the table, where it shows constraints on document IDs, collection IDs, field names and field paths.

Of course, the quota document. :-) Thanks, Ani!

Of course, if you couldn't find it, we can probably do better to make it easy to find. I'll see about adding at least a note somewhere in the guide.

True enough, though I don't know there's an obvious place for it; I couldn't think where to look past DocumentReference.collection, CollectionReference.document, etc. I mostly just Googled [firestore path allowed characters] and similar. Maybe this thread will help people find it.
