wcwidth is a Python library that calculates the display width (number of columns) a Unicode string occupies in a terminal. It counts full-width characters such as Hangul and Chinese characters as 2 columns and combining or control characters as 0 columns, and is used to align strings and place line breaks precisely in terminal UIs. It plays the same role as the C standard function wcwidth() and includes data tables for each Unicode version.
Measures the displayed width of unicode strings in a terminal.
