Lines containing unicode characters differ in height

[Tyriar]

Using the demo, lines with CJK characters at 24px, regular lines are 18px, and my prompt character is 20px.

This is the reason that on my computer the size of the terminal increases every time I press enter; because the ❯ character is being added, pushing out the height of the line.

@Tyriar are you aware of any way we can fix this? Could we somehow (based on font-size I guess) know what is the appropriate line height to set, in order not to have lines with variant line heights?

The way I'm probably going to approach a fit for vscode at least which allows a configurable font-size and line-height, is to make the default line-height a fixed pixel size and set it as the height as well. Setting height and line-height forces all chars to be aligned the same and all lines to be the same height.
