Escape html & non-ascii chars with javascript

Question

OK, so I need to replace all <, & and > plus all non-ascii characters with their html-entity counterparts. I've tried Underscore.string.escapeHTML but that didn't seem to touch the non-ascii chars.

For example I need this:

<div>föö bär</div>

converted into this:

<div>föö bär</div>

Obviously auml and ouml are not enough. I need a valid ascii string no matter what buttons the users chooses to push, or heaven forbit, even writes with some moonspeak keyboard.

For the purpose of your needs you have to use htmlEncode function.

They define a number of other useful functions within the object:

HTML2Numerical: Converts HTML entities to their numerical equivalents.

NumericalToHTML: Converts numerical entities to their HTML equivalents.

numEncode: Numerically encodes unicode characters.

htmlDecode: Decodes HTML encoded text to its original state.

htmlEncode: Encodes HTML to either numerical or HTML entities. This is determined by the EncodeType property.

XSSEncode: Encodes the basic characters used in XSS attacks to malform HTML.

correctEncoding: Corrects any double encoded ampersands.

stripUnicode: Removes all unicode characters.

hasEncoded: Returns true if a string contains html encoded entities within it.
