Re: linux/gcc, apostrophs display problem

Hi,

"""

"""
into .emacs and.... it works! Hey, great! Unbeliable. Do I understand
this...?
Sort of...
  #x53978
is the emacs-internal represenation of that apostroph? What _is_
emacs' internal representation of characters? Can I use this also to
replace all tabs with '*' or all spaces with '_'? lets try...
"""
(aset standard-display-table ?U [?X] )

Cool, making an "X" from a "U" :-). Ok, understuud. Thanks, that was
exacltly what I wanted to know.

I do not recognize the "?..." and "[?...]" form of the arguments here,
they came from the documentation of "standard-display-table". Can I
trouble you to give me an additional hint here?

thanks,
tschau, towi.
