Emoji support was added in gdb 17.

The code deciding whether emojis are emitted is:
...
bool
emojis_ok ()
{
  if (!cli_styling || emoji_styling == AUTO_BOOLEAN_FALSE)
    return false;
  if (emoji_styling == AUTO_BOOLEAN_TRUE)
    return true;
  return streq (host_charset (), "UTF-8");
}
...

There's nothing specific to the active interpreter.

So in the case of your example, the factors that enable emojis are:
- cli_styling == true
- emoji_style == AUTO_BOOLEAN_AUTO
- host_charset () == "UTF-8"
