Yeah, it definitely should keep the symbol intact. But that to make sure is an issue of the FUDI encoding. I don't type backslash escapes and I also do not want them to be displayed. The backslashes are not part of the payload, unless I type them explicitly. > But I think print should keep it, in the same way we also need to > keep it for message boxes. > > Outside the context of a symbol box, it is important to differentiate > if we have, for instance, a list where one of the items contains an > escaped space. > > like, the message: > > | list one\ item two < > > has two atoms "one item" and "two", and print should be able to tell > us that. Yeah, that's the FUDI encoding of a list containing two symbols. > Now, I don't know about the new list box. What if we want to create a > list with an escaped space? It seems like a special and > different case/context of a symbol box. Yeah, obviously list boxes are for lists and symbol boxes for symbols. I think for list boxes to be effective they need to show the FUDI encoded value, which means displaying the escaping character. > By the way, I've been testing it and it seems we can do this by > putting the escaped character ourselves. That seems correct. But it > would be different than the symbol box and maybe I guess it shouldn't > be too problematic that the symbol box also shows escaped characters. Yes, it is, imho, it is dead-ugly and confuses the distinction between payload and encoding. I'm pretty happy that Python doesn't only print "b'Z\xc3\xbcrich'" when I intend to print "Zürich". > They're not that common and we can document why this happens when it > happens. That would be confusing things even more. Roman
