copy-paste a string of chinese characters not working about termbox-go

[nsf]

Honestly, I have no idea how chinese input works. Termbox doesn't have "official" support for wide characters, unless someone implements it properly. It's a tricky question because it also needs to work on windows.

Wow, that was fast, thank you man!
The good thing is that if you write characters one by one and then hit space, it works. Of course it's a very slow input method.
Well, I think I'll have to continue using the normal console for the input but maybe I still can use termbox to review the data later.
Thanks again!

The problem is that the character you are pasting wide, so editbox is probably not quite right here. That's just a demo program, so I wouldn't worry about it very much.

If you know you're going to be working with wide characters, you need to be careful in rendering them, understanding that each character may consist of multiple bytes, and may occupy either 1, 2, or even 0 cells. Its hard to get this right without some care, and the Asian locales are the most confusing to deal with.

Actually, even more confusing are bidi languages... :-)

So it turns out not to have been as difficult as I feared -- provided we elide combining characters. Double wide characters are fairly straight forward -- as seen above. Please give it a try.

Hi there,

In order to make things more clear, I can provide an example:

You can see there seems to be some width calculation error , the characters are not being fully displayed .

We are testing your fix right now, will let you know.

Feel free also to give github.com/gdamore/tcell/termbox a shot. I think it has a good chance of Just Working for you. And it supports wide characters properly I think. (And if you use the parent package instead, tcell, you get nice support for even combining characters.)

here are another demonstration.

@gdamore okay! we are giving it a shot! Thanks again for quick reply!

@thefallentree Termbox it self is not wrong. Error was in the example file. I just fixed it.
