* <p><strong>Note:</strong></p>
* <p>
* In p5.js 2.0, <code>textWidth()</code> may return <code>0</code> when
* measuring a string that contains only whitespace characters,
* such as a single space (<code>' '</code>). In earlier versions,
* whitespace contributed to the measured width.
* </p>
* <p>
* This behavior differs from <code>fontWidth()</code>, which measures
* individual glyph widths, including whitespace.
