Hi I am having a discussion with emacs developer about an emacs bug that is related to multi-column characters, e.g. many emojis.
My first question is to those who have intimate knowledge about the Linux console: My understanding is that Linux has no support of any kind for displaying multi-column characters in a VT. Is this true? If not, what is this support? The second thing is related to BRLTTY's /dev/vcsu-support. If I write on the console a multi-column character followed by a space, BRLTTY does not show this space on the braille display, even when it is visible on the screen. So writing <PERSON WITH FOLDED HANDS> and a space in the console results only to the output of the emoji on the braille display. The cursor is not moved, and is incorrectly shown right after the emoji. If I set screen-parameters lx:Unicode=no in brltty.conf, this problem disappears. Of course this could also be a kernel issue in the /dev/vcsu-implementation. -- Aura _______________________________________________ This message was sent via the BRLTTY mailing list.
