 Servers MUST limit this to 512 bytes, returning code 400 to clients that try to set a longer one. Clients MUST NOT attempt to set a longer `uri`. Clients SHOULD NOT display any received `uri` that is longer.

+In addition to URI validation, this field MUST NOT contain whitespace, and MUST contain a colon. This prevents just inserting text like `hello world`, which is apparently a valid URI.

 ## String cleaning

 Certain characters are banned in user data strings. Servers MUST reject attempts to set data strings that contain these characters, and clients MUST NOT upload data strings that contain these characters. Clients MAY strip out these characters when user attempts to upload them, instead of returning an error to the user. Clients SHOULD strip these out from statuses it downloads.
