However, a validator such as xmllint or HTML Validator should easily find all cases of these, along with a few cases the simple search will mix. Embedded JavaScript presents a problem here. JavaScript does not recognize < as a less-than sign. Inside JavaScript, you have to use the literal character. A less-than sign can usually be recast as a greater-than sign with arguments reversed.

https://stackoverflow.com/questions/9010678/html-should-i-encode-greater-than-or-not-gt

word choice – What is the name of the symbols < and ... https://english.stackexchange.com/questions/255262/what-is-the-name-of-the-symbols-and I know that ^ is called a caret, but this doesn't seem to apply to the similarly shaped but nonetheless different < and > symbols. The only names I’ve heard them called is the less-than sign and the greater-than sign, but those names seem rather informal and apply only to their use in math.The symbols are used in other contexts as well, so it seems they would have less specific names.
