You can tell if the whole file was downloaded using the HTTP-protocol by using the Content-Length header.

I think the creators of the nex-protocol, gemini-protocol, and other similar protocols felt something like that was too complex.

I wonder if using the ␄ control character to mark the end of the file was considered.

End of Transmission (␄) = 0x04

And used ␛ control character to escape when ␄ (or ␛) appeared in the data.

Escape (␛) = 0x1B

The nex-protocol specification is very short.

THE NEX PROTOCOL

Nex is a simple internet protocol designed for distributed document
retrieval. It's inspired by gopher and gemini.

Servers should listen on port 1900. Afterall, night falls at 7pm!
Users connect and send the server a path which may be empty. The
server responds with text or binary data and close the connection. No
state is retained.

Document content is returned as-is. Directory content use plain text
with a special syntax where each line beginning by "=> " followed by a
URL is considred a link. The URL can be absolute or relative. Here are
examples:

=> nex://my-site.net
=> about.txt
=> ../nexlog/

Clients can assume that an empty path or a path finishing with / is a
directory. A document should be displayed based on the path's file
extension. When there is no extension, plain text is assumed.

Here is an example telnet session:
telnet nex.nightfall.city 1900
hello-world.txt

Hello world!
