<h2>About Unicode.run</h2>
<p>Text is <i>unexpectedly</i> complicated. Use Unicode.run to debug text.</p>
<p>Here are some things you can do here:</p>
<ul>
<li>See each code point’s escape code in a variety of programming languages.</li>
<li>See the “length” of the text as it would be reported in different programming languages.</li>
<li>See when characters (technically “extended grapheme clusters”) are composed of multiple code points.</li>
<li>Click code points in the debugger output to highlight them in the text. (In Firefox you can also select text to highlight the code points in the debugger output.)</li>
<li>Switch between the text and its UTF-32 or UTF-16BE hex encodings at the top of the page.</li>
<li>See where text changes direction in bidirectional text, and get warnings when text direction depends on where it is used. Mirrored glyphs in bidirectional text are also noted.</li>
<li>Get warnings about hidden code points that can alter the display of the text (see <a href="https://trojansource.codes/">https://trojansource.codes/</a>), invalidly placed combining code points, invalid code points, and characters that are not in normalized form.</li>
</ul>
