Including ? in a document ID is interpreted as the beginning of the query string

[DavidDTA]

Document and collection IDs should be made URL-safe

@DavidDTA Can I see the example of this case?

Elm internally handles URI encoding in some ways, so I am just looking for what causes this issue.

[DavidDTA]

It looks like the elm code does not do as much encoding as one would hope:

Url.Builder.relative ["foo", "ba?r"] [] -- "foo/ba?r"

[DavidDTA]

It looks like there is an open issue in elm/url for this: elm/url#25
