cursor position in opencode is wrong

[jixiuf]

After entering a character in opencode, the cursor should be positioned after the character, but currently it is positioned on the character.

in ghostel:

in alacritty:

Since I can't reproduce it locally, can you give me as much detailed info as possible:

• is this the latest ghostel version?
• do you have evil mode activated
• was this always the case or is that a recently introduced bug? if so, do you suspect after updating ghostel or opencode?
• in your example, when you type another character, is it really inserted before the 'h' or just a cursor/display bug?

please share as much info as possible.

yes

no. I use emacs -Q -L . -l ghostel.el

* was this always the case or is that a recently introduced bug? if so, do you suspect after updating ghostel or opencode? 

always the case (it exists before ghostel v0.1), I don't think it is the bug of opencode, it works on alacritty

* in your example, when you type another character, is it really inserted before the 'h' or just a cursor/display bug?

not before the 'h' , just a cursor/display bug.

I thnks the bug is related to the bar ┃ . I copy the ┃ and paste it in a new thostel terminal, then after insert a char after the bar, the cursor position is wrong again .

Hmm. Is that a special opencode theme that I could use to reproduce?
When I paste ┃ into the shell all works normal.

@jixiuf can you try this PR #90 (needs a native module build).
(This is untested if this actually solves the bug as I can't reproduce it locally)

wired .just the default theme
