is there utf8 support?

[mendisobal]

Do you plan utf8 support?

I don't have time to support it now.

In linux I managed to have utf8 running by simply linking to ncursesw. There are some issues with drawing on short views, but it may be simple to solve it with Lua 5.4 or with a library such as https://github.com/starwing/luautf8

I will investigate it further when I have the time

We also need to consider pdcurse with wchar.

I also need to consider the compatibility with xmake, because xmake also uses ltui, https://github.com/xmake-io/xmake/tree/master/xmake/core/ui

But xmake's ltui does not need luautf8, because its runtime rewrites built-in lua modules such as io/string, and has added support for utf8.

Thanks

this pr #27 solves the splitting of utf8 strings and also permits utf8 input in textedit views.
Both ncurses and pdcurses use codes greater then 0xFF for special key codes, hence the limitation for codes < 0x7f is not strictly needed AFAIK

We also need to consider pdcurse with wchar.

I've submitted a pr #28 with the required flag for pdcurses, but I didn't test it, I got access to a windows machine but didn't set up the environment yet. I tried to use ltui over ssh (putty), though. If the utf8 support comes to be, it would be nice to permit the user to choose utf8 glyphs instead of ACS characters:

the utf8 characters and mouse events work fine over ssh. Great for embedded applications!

Thank you very much, as long as you can ensure compatibility with xmake's ui module, only modify curses/pdcurses, or replace some native io interfaces, I welcome pr.

But I don't want to add new c modules and interface calls to ltui. Because when these patches are merged into xmake, these c libraries will also be added.
