最佳答案

It's a unicode character. In this case \u003C and \u003E mean :

U+003C < Less-than sign

U+003E > Greater-than sign

See a list here

Those are unicode escapes. The general unicode escapes looks like \uxxxx where xxxx are the hexadecimal digits of the ASCI characters. They are used mainly to insert special characters inside a javascript string.

It is a unicode char \u003C = <

That is a unicode character code that, when parsed by JavaScript as a string, is converted into its corresponding character (JavaScript automatically converts any occurrences of \uXXXX into the corresponding Unicode character). For example, your example would be:

Browse Interests\{\{/i}}</a>\n        </li>\n  \{\{#logged_in}}\n

As you can see, \u003C changes into < (less-than sign) and \u003E changes into > (greater-than sign).

In addition to the link posted by Raynos, this page from the Unicode website lists a lot of characters (so many that they decided to annoyingly group them) and this page has a (kind of) nice index.

Unicode all starts with \u e.g. \u0001

In JavaScript

unescape("\u003c")

Although unescape() is not strictly deprecated (as in "removed from the Web standards")
