Hello,
I would like to determine the (max) number of bytes a character/units in
a certain encoding consumes. Unfortunately there does not seem to be an
interface exposed for it (or I just don't see it).
I'm doing it this way:
(defun max-code-units (encoding)
(babel::enc-max-units-per-char (babel::get-character-encoding
encoding)))
(defun code-unit-size (encoding)
(ash (babel::enc-code-unit-size (babel::get-character-encoding
encoding)) -3))
(defun max-code-size (encoding)
(let ((e (babel::get-character-encoding encoding)))
(* (babel::enc-max-units-per-char e)
(ash (babel::enc-code-unit-size e) -3))))
Is this a good idea to to that way? Please comment.
Thanks,
Frank
