This was a bit of a PITA to run down; the essence of the problem was that the shaper was returning an x_advance of 0 for U+3000, which caused wezterm's shaping layer to elide that glyph. I eventually tracked down the x_advance to be the result of scaling by an x_scale of 0, which in turn is the result of harfbuzz not knowing the font size. The critical portion of this diff is the line that advises harfbuzz that the font has changed after we've applied the font size. The rest is just stuff to make it easier to debug and verify. This: ``` printf "x\u3000x." ``` Now correctly renders on screen as "x x". fixes: #1161 |

wezterm-term
This crate provides the core of the virtual terminal emulator implementation used by wezterm. The home for this crate is in the wezterm repo and development is tracked at https://github.com/wez/wezterm/.
It is full featured, providing terminal escape sequence parsing, keyboard and mouse input encoding, a model for the screen cells including scrollback, sixel and iTerm2 image support, OSC 8 Hyperlinks and a wide range of terminal cell attributes.
This crate does not provide any kind of gui, nor does it directly
manage a PTY; you provide a std::io::Write implementation that
could connect to a PTY, and supply bytes to the model via the
advance_bytes method.
The entrypoint to the crate is the Terminal struct.
