Original Pull Request: https://github.com/microsoft/terminal/pull/3371

State: closed
Merged: Yes

Summary of the Pull Request

The LineChar array was used to hold a set of the Unicode characters required to draw the borders of a box. The array was never updated with different values, so there was no need for that level of indirection. This PR gets rid of the LineChar array and just uses the appropriate Unicode constants directly.

PR Checklist

Detailed Description of the Pull Request / Additional comments

The only place the LineChar values were used was in the _DrawBorder method of the Popup class, so I've just replaced all of those references with the appropriate Unicode constants, then removed the LineChar array, and it's initialization code, from the SCREEN_INFORMATION class.

Validation Steps Performed

I've checked that the borders still render correctly by viewing the command history dialog (F7) in a cmd.exe shell.
