Zero Width Spaced Nicks

[Ryuuusuke]

We like matterbridge because It let us to bridge discord message without having us to open discord. But I found that ZWSP Inside a nick will be count as regular space

So zero width spaced nick should be like this

<Lorem>

become like this inside the client

<L orem>

I included secreenshot here

Some reference
42wim/matterbridge#175

Love your client btw. Pretty Cool :3

Thanks for reporting.

I think this function needs an update to not increment the X coordinate on zero-width chars:

tiny/crates/libtiny_tui/src/termbox.rs

Lines 6 to 22 in 8747b6b

	pub(crate) fn print_chars<C>(
	tb: &mut Termbox,
	mut pos_x: i32,
	pos_y: i32,
	style: Style,
	chars: C,
	) -> i32
	where
	C: Iterator<Item = char>,
	{
	for char in chars {
	tb.change_cell(pos_x, pos_y, char, style.fg, style.bg);
	pos_x += 1;
	}
	pos_x
	}

I can try fixing this later this evening, but if you're up for it in the meantime feel free to update that function, and if it fixes the issue a PR would be nice, too 😄 You can use the unicode_width crate, which we already depend on.

Just an update: I spent some time trying to debug this but it turned out to be a bit more involved. The code shown above is not used to draw nicks.
