In HTML, hidden characters are represented by specific entity codes that don't display as visible text. These codes are used to insert special characters, such as line breaks or tabs, into web pages.
The most common HTML entity for a hidden character is the non-breaking space, which is represented by the code ` `. This code inserts a space that can't be broken across lines, ensuring that text wraps around it properly.
Using hidden characters in HTML can be useful for formatting text and maintaining readability, but they can also be used to hide sensitive information from view.

What are Hidden Characters?
Hidden characters are a type of Unicode character that doesn't appear on the screen but can be used to represent empty space without using the space key. They are often used in document editors to keep phrases together or to insert no-break spaces.
There are many types of hidden characters, including whitespace Unicode characters, blank characters, and invisible text or invisible characters. These characters have specific meanings and can be used in various applications instead of regular empty spaces.
Some examples of hidden characters include the space (U+0020), no-break space (U+00A0), and ideographic space (U+3000). Here are some examples of whitespace Unicode characters:
Definition

Hidden characters are blank Unicode characters or text types, such as U+0020, U+00A0, or U+FEFF, that don't appear on the screen.
These characters are part of the universal coded character set, known as Unicode, which contains thousands of characters.
Whitespace characters, like the pilcrow or non-breaking space, are used to represent empty spaces without using the space key.
They're often used in text editors to indicate the presence of formatting elements, but they can't be printed with the document.
White fonting is a way to insert hidden words into a document, making them invisible and unreadable, but still present on the page.

Invisible Text
Invisible text, also known as hidden text, is a feature that allows you to conceal certain words or phrases within a document or text.
You can use invisible text to prevent unintended word breaks, such as using a zero-width space () to keep "WordBreak" intact unless the layout forces a break.
Invisible text can also be used to represent an empty space without using the space key. Whitespace characters, such as U+0020, U+00A0, U+FEFF, etc., do not appear on the screen but are part of the Unicode character set.
Some common non-printing characters in text editors include pilcrow, space, non-breaking space, tab character, and pilcrow. These characters indicate the presence of formatting elements but cannot be printed with the document.
To insert hidden words into a document, you can use white fonting, where keywords are written in a white font, making them invisible. However, this can make the text unreadable.
If you need to add non-breaking spaces, line breaks, or hidden characters to control spacing in text, you can use HTML entities.

Character entities in HTML are special codes used to display reserved characters that have specific meanings in HTML markup, avoiding conflicts or display issues.
Using an HTML entity for a hidden character is a great way to add non-breaking spaces, line breaks, and hidden characters that control spacing in text, ensuring that the spaces remain intact even when the text wraps.

Examples
HTML entities are used to represent hidden characters in HTML documents.
The entity is used to insert a soft hyphen, which is a visible character that is only visible when a line of text is broken at the hyphen.
In HTML documents, the entity is used to insert a zero-width non-joiner, which is a character that prevents adjacent characters from being joined together.
The   entity is used to insert a thin space, which is a small amount of space that is used to separate words or phrases.
Using HTML entities for hidden characters can help improve the readability and layout of HTML documents.

Encoding
Encoding is a crucial step in handling user-generated content to prevent security vulnerabilities like cross-site scripting (XSS).
Encoding special characters into entities prevents browsers from running malicious JavaScript code.
To encode HTML entities, you can use JavaScript, which will convert special characters into their corresponding entity codes.
This outputs: (example of encoded HTML entities in JavaScript).
HTML character encoder converts all the ASCII characters to their HTML entities, making it easier to display reserved characters and invisible characters.
Entities are frequently used to display characters that are difficult to type with a standard keyboard.
The HTML entity code of a character begins with an ampersand (&) and ends with a semicolon (;).
For example, the entity code of the less-than sign is "<".
