I need a way to identify certain strings in HTML markup. I know what the strings are, but it is possible that they could be substrings of other strings in the document. To find them, I output a special delimiter character (currently using \032). On page load, we go through the HTML and record the location of the strings, and remove the delimiter.
Unfortunately, most browsers show the delimiter character until we can find and remove them all. I'd like to avoid that if possible. Is there a character or string that will be preserved in the HTML content (so a comment wont work) but wont be visible to the user? It also needs to be something that is fairly unlikely to appear next to a string, so something like wouldn't work either.
EDIT: Sorry, I forgot to mention that the strings will be in attributes, so any sort of tag wont work.

Invisible character is ALT+255. You need 255 typed on the keypad. Not the one above QWERTY keys. You can use desktop keyboard to do this.

On the off chance that this already appears in your text, double it up (eg: ‌‌mytext‌‌
Edit in response to comment: works in Firefox 3. Note that you have to search for the Unicode value of the entity.
