Hi,
I am on Fedora 34 now (apl SVN: 1198:1472M)
The apl font partially fails to work with keyboard layout apl.
The "over strike characters" ⌽⍉⍟⍝⍱⍲ ,when entered in a terminal,
appear in half....
The left half of the character is being displayed when entered.
The right half appears when space bar is being pressed.
Anny further character entered is being offset by one.
That is ⌽[space]ABC -> ends up as ⌽BC where space bar
"overlays" character A!
The Apl-Session, terminal, emacs, vi are affected too. slikedid,
Firefox are OK.
If changing the layout via setxkbmap -layout "apl" I get
���� instead of ⌽⍉⍟⍝.
The � are being displayed the same way as described above: Left half
character, [SPACEBAR] right half of the character.
I installed apl from the repository to verify the behavior - that
segfaults.
The font-manager shows
⍝ APL FUNCTIONAL SYMBOL UP SHOE JOT U+235D
So there is nothing special about this and 'normal' UTF-8
characters.
The terminal font is set to latarcyrheb-sun16 in /etc/voconsole.conf.
Changing the terminal font to either Unifont-APL8x16-12.1.02 or
NotoSansMono did not help.
Emacs:
After some 'fiddling around' font changes with emacs M-x
menu-set-font will display ⍝ in one go,
Char ⍝ will be displayed for different fonts - even if the
font-manager does not show it.
Char ⍝ with font NotoSansMono selected will be displayed in one shot
but with additional spacing to the left and right.
Char ⍝ with Unifont selected will be displayed w/o spacing.
( The console fonts and the content of menu-set-font are
different...)
Hopefully some one has an idea where / how to dig deeper into the
problem.
Best Regards
Hans-Peter
Is there / some where an experiment going on to 'improve' character
composition?
