Accept all characters in direct lexical form?
Here is a simple question, but perhaps not a simple answer:
Do we allow non-printing characters within a character literal?
For example, we now accept chars like:
>> to integer! #"^J"
But, what if the ^J is actually a char code 10?
Currently, R3 allows that. However, CureCode #1232 reports this feature as a bug.
Arguments can be made both ways, for and against.
If we decide not to allow it, then we should not allow any such literals below U+0020. (As for possible unprintable literals above that, I think we need to accept them all.)
Not that this does not affect how strings and files deal with such characters. We're only talking about the char literal format here.
