I was under the impression you wanted to achieve this:
asql> select hex('abc' || X'10FFFD');
hex('abc' || X'10FFFD')
-----------------------
61626310FFFD
asql> select length('abc' || X'10FFFD');
length('abc' || X'10FFFD')
--------------------------
6
asql> select typeof('abc' || X'10FFFD');
typeof('abc' || X'10FFFD')
--------------------------

Note sure how that's relevant Hick. We don't need a blob, but a integer for
char(). I was obviously talking about *number* literals (prefixed with 0b, 0,
0x for binary / octal / hexa), not blob literals.
I'd be +1 to having char() also accept blobs (1 to 3 bytes long) instead of
integer, since x'10FFFD' is closer to U+10FFFD than 1114109 is.
But Dr. Hipp would need to agree with that. Until then, 1114109 it must be. --DD
