I'm not sure what you mean. For an illustration, my terminal does not print anything for them.

    $ printf "qq\36\37text\n"
    qqtext

*Update/Aside:* "My terminal", in this case, was `tmux`. Ghostty, OTOH, prints spaces instead of RS or US.

Unicode does have some symbols for every non-printable ASCII character, which you can see as follows with https://github.com/sharkdp/bat (assuming your font has the right characters, which it probably does):

    $ printf "qq\36\37text\n" | bat -A --decorations never
    qq␞␟text␊

Here, `␞` is https://www.compart.com/en/unicode/U+241E, one of the symbols for non-printable characters that Unicode has; different fonts display it differently. See also https://www.compart.com/en/unicode/block/U+2400.

Is there some better representation it has?

Yes, I did mean the ␞ U+241E unicode symbols that represent separators. And as your `| bat` example shows, they can also be displayed in the terminal.

If you meant the default should always be symbolic, not sure, like newline separator isn't displayed in the terminal as a symbol, but maybe that's just a matter of extra terminal config
