IBM extended character set

IBM extended character set

[harry weston]

Hello

I have searched the 'net, but cannot find out how to incorporate into emacs the symbols from the IBM extended character set that draw boxes of single or double lines. It used to be easy on my old Epson dot-matrix printer. My failure to locate it is most likely because I don't know exactly what to look for among the ISOs and all that. I'll be very grateful for any help your can give,

Very best wishes, and thanks for offering this service, Harry Weston

Do you mean ibm850 or ibm866? Or cp437 or such?

These characters are already supported by Emacs, they are on Unicode
codepoints u+2500 to u+25ff.  You can insert them with C-x 8 RET,
e.g. "C-x 8 RET 2500 RET"

These characters are in unicode, and emacs 23 uses unicode, so you can
insert them directly.   That is, you can bind them to your X keyboard
with xmodmap.

For example, I have in my ~/.xmodmap:

!------------------------------------------------------------
! Numerical Keypad
!------------------------------------------------------------

! Second line:
!keycode  77 = Num_Lock        Pointer_EnableKeys
keycode  77 = Num_Lock        
keycode 106 = KP_Multiply     XF86_ClearGrab
keycode  63 = KP_Divide       XF86_Ungrab
keycode  82 = KP_Subtract     KP_Subtract 0x1002500 0x1002550

! Third line:
keycode  79 = KP_Home         KP_7    0x100250C  0x1002554
keycode  80 = KP_Up           KP_8    0x100252C  0x1002566
keycode  81 = KP_Prior        KP_9    0x1002510  0x1002557

! Fourth line:
keycode  83 = KP_Left         KP_4    0x100251C  0x1002560
keycode  84 = KP_Begin        KP_5    0x100253C  0x100256C
keycode  85 = KP_Right        KP_6    0x1002524  0x1002563
keycode  86 = KP_Add          KP_Add  0x1002502  0x1002551

! Fifth line:
keycode  87 = KP_End          KP_1    0x1002514  0x100255A
keycode  88 = KP_Down         KP_2    0x1002534  0x1002569
keycode  89 = KP_Next         KP_3    0x1002518  0x100255D

! Sixth line:
keycode  90 = KP_Insert       KP_0
keycode  91 = KP_Delete       KP_Decimal
keycode 104 = KP_Enter 


So I can insert: 

┌─┬─┐
│ │ │
├─┼─┤
│ │ │
└─┴─┘
╔═╦═╗
║ ║ ║
╠═╬═╣
║ ║ ║
╚═╩═╝

by typing: Mode_switch KP_1, etc.

Of course, you can also insert these characters directly in emacs:

(insert (string #x250C #x2500 #x2500 #x2500 #x2510 10 
                #x2502 32 32 32 #x2502 10
                #x2514 #x2500 #x2500 #x2500 #x2518 10))
┌───┐
│   │
└───┘

For example, you could bind them to keys.

you'll need to give us some details. e.g. do you have a image
(screenshot) of the character? Most people today isn't familiar with
ibm charsets.

also, am certain that all ibm charsets in any version should be in
unicode. So, your problem is simply finding the right unicode, if i
understand it correctly. Not sure what you mean by “incorporate”.

you might find your char in the “shapes” file in the following:

• xub Unicode Browser mode for Emacs
  http://xahlee.org/emacs/unicode-browser.html

the following might help on some issues of input, code point, etc.

Box drawing characters are at code points 2500 to 2580 hex. A good free
tool that shows character coverage of ttf fonts is Babelmap. It is also
a general purpose Unicode exploration tool. It shows official glyph
names even if you don't have a font to display the glyphs themselves.


http://www.babelstone.co.uk/Software/BabelMap.html

There must be something like this for Linux.

ucs-insert function will insert arbitray unicode glyphs into buffer:

(ucs-insert "2530") -> ┰
