Testing the behavior of different unicode graphemes in terminals and checking if the assumed length is fitting to the printed representation.
Uses the unicode_width crate for the width estimates. Also check for potential interactions with ANSI coloring.
To make it feasible to check many terminal emulators and platforms
automate the counting of columns. Assumes the examples are fitting well
into a row of a standard terminal (e.g. 80x24).
Supports both check without ansi additions (default) and with ansi
background and foreground color changed (--full).
Manual checking is possible via --manual
