<div class="desc"><p>Returns a fresh string with every ASCII letter <code>a</code>-<code>z</code> turned to uppercase; other bytes pass through unchanged. The input is left untouched. Use it to normalize input before comparing, or to shout a label. This is ASCII-only — accented and non-Latin letters are left as-is; for full Unicode case mapping use <code>Unicode.upper</code>.</p></div>
