OK, I did not check in the "higher" Unicode regions, and I did not
check in an UTF-8 encoded buffer, and I did not input so long numbers
I cannot compute, I was still in my simple ISO 8859-X test files
(your example works for me too in an UTF-8 encoded buffer). After
launching GNU Emacs 22.0.50 with -Q the phenomenon seems to be that
input like
C-s C-q <[23][0-7][0-7]> RET
is interpreted as trying to "name/point to" an ISO 8859-1 encoded
character. For example:
C-s C-q 245 in ISO 8859-16 does not find ``„´´ (U+201E) – mini-
buffer tells me that ``¥´´ (\245 in ISO 8859-1) cannot be found.
C-s C-q 241 RET searches for ¡.
C-s C-q 242 RET searches for ¢.
C-s C-q 243 RET searches for £.
C-s C-q 244 RET searches for ¤ (CURRENCY SIGN, U+00A4).
Evaluating (unify-8859-on-decoding-mode t) does not change this
specific behaviour.
Which is the formula to map octal 0156772 to a Unicode slot/position?
Octal 0156772 is DDFA in hex, which is different from 5B57, 字's
position in Unicode. Or: how can I find the octal value for a given
Unicode slot (U+ABCD)? There is probably some function for this
purpose ...
