choose radix for control and non displayable characters

choose radix for control and non displayable characters

[Sébastien Kirche]

Hi,

i  have looked for  a mean  to change  the radix  of control  characters and
characters that are  not displayable with the current  fontset, but it seems
that it is hard-coded (xdisp.c / get_next_display_element() ?).

I think it is some way inconsistent  as i can choose the radix for the input
of quoted characters with read-quoted-char-radix.

Could  someone consider  about  to add  a  variable to  choose that  display
radix ? It is easily feasible ?

Regards.

No need to make the C code more complex:

   (let ((n 128))
     (while (< n 256)
       (aset buffer-display-table n (format "\\x%2x" n))
       (setq n (1+ n))))


Let's not forget that chars in the 128-255 range should only ever appear in
buffers containing binary data (and otherwise in cases where there was
a problem, such as when an email is badly labelled).
