Hidden text is computer text that is displayed in such a way as to be invisible or unreadable. Hidden text is most commonly achieved by setting the font colour to the same colour as the background, rendering the text invisible unless the user highlights it. Hidden text can serve several purposes.
In classical cryptography, a null is an extra character intended to confuse the cryptanalyst.In the most common form of a null cipher, the plaintext is included within the ciphertext and one needs to discard certain characters in order to decrypt the message (such as first letter, last letter, third letter of every second word, etc.) [1] Most characters in such a cryptogram are nulls, only ...

The left-to-right mark (LRM) is a control character (an invisible formatting character) used in computerized typesetting of text containing a mix of left-to-right scripts (such as Latin and Cyrillic) and right-to-left scripts (such as Arabic, Syriac, and Hebrew). It is used to set the way adjacent characters are grouped with respect to text ...
