Alternative representations will appear in all the other boxes. You can also do the same in any grey box, if you want to target only certain types of escaped text. You can then cut & paste the results into your document. <img src="selectall.png" alt="Select" /> selects all the text in a box (useful for deleting), and <img src="copy.png" alt="Copy"/> copies the text to the clipboard, if your browser supports that. See the <a href="help">help page</a> for other options.</p> <p><b class="leadin">Worked example.</b> The text in the field with a green background currently contains a variety of escapes. Normally you would simply click on the <code>Convert</code> button just above the field to show the various escape formats below. Note, however, that this (unusually convoluted) text represents two characters using just a code point number – therefore, for this particular example, you should select <code>Treat bare numbers as Hex code points</code> (or decimal) to convert those numbers as well as the other escapes. You should also ensure that the checkbox next to <code>Convert \n etc</code> is selected, in order to convert the <code>\n</code> and <code>\t</code> escapes.</p> <p>After selecting those options, click on the <code>Convert</code> button.</p> <p>You will then see the conversion results in the grey boxes. You can use checkboxes alongside many boxes to tweak the results.
