string-width

string-width only calculates the width of strings and does not handle more complex text formatting or alignment tasks.

The tool primarily supports left-to-right text, which may lead to incorrect width calculations for right-to-left languages like Arabic and Hebrew without additional custom handling.

string-width calculates the number of columns based on character widths but does not consider how different fonts might render these characters, which can lead to discrepancies in actual display width.

The tool may struggle with Unicode combining characters that modify the preceding character, potentially leading to inaccurate width calculations for such text.
