htmlEscape
The $htmlEscape function converts HTML specific control characters so that they are no longer interpreted as HTML code.
For example, a quotation mark (') is converted to " and a lowercase character (<) is converted to <.
If such a text is drawn as HTML (e.g. label element, grid cell), then these characters would be output as text instead of being interpreted by the browser as HTML.

Return value
Returns the passed text with encoded HTML specific control characters.
Example
In a label element (which interprets and renders HTML) a text is to be output, which should not be interpreted as HTML.
The text is 'Please specify<from> and <to>!'.
The representation in a label element interpreted as HTML would now look like this:
'Please specify!'
Because <from> and <to> were interpreted by the browser as HTML markup tags and therefore no longer appear as text.
This can be prevented by the following calculation expression.
$htmlEscape(Please specify <from> and <to>!)The output on the screen is now as desired:
'Please specify<from> and <to>!'
Because the browser evaluates the following text 'Please <from> and <to> specify!' and therefore finds no HTML markup.
