For instance, children could decode a phrase such as “Pat the fat rat” if they had been taught the letter-sound associations for each letter—that 'p' stands for the sound /p/, 'a' for the sound /a/, etc. Generally, decodable text is used in programs that have a strong phonics emphasis. [1]
Likewise, many early operating systems do not support multiple encoding formats and thus will end up displaying mojibake if made to display non-standard text – early versions of Microsoft Windows and Palm OS for example, are localized on a per-country basis and will only support encoding standards relevant to the country the localized version ...
The key to decrypt a message requires no more knowledge than the fact that ROT13 is in use. Even if secrecy does not fail, any alien party or individual, capable of intercepting the message, could break the code by spending enough time on decoding the text through frequency analysis [2] or finding other patterns.
The key text was the Harry Potter books, but the messages were sent via a The Lord of the Rings forum to make the key text harder to identify. In Lost: Mystery of the Island, a series of four jigsaw puzzles released in 2007, a book cipher was used on each puzzle's box to hide spoilers and reveal information about the show to the fans.
QR codes which contain binary data will sometimes store it encoded in Base64 rather than simply storing the raw binary data, as there is a stronger guarantee that all QR code readers will accurately decode text, as well as the fact that some devices will more readily save text from a QR code than potentially malicious binary data.
Punched tape with the word "Wikipedia" encoded in ASCII.Presence and absence of a hole represents 1 and 0, respectively; for example, W is encoded as 1010111.. Character encoding is the process of assigning numbers to graphical characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using computers.

This led to the idea that text in Chinese and other languages would take more space in UTF-8. However, text is only larger if there are more of these code points than 1-byte ASCII code points, and this rarely happens in the real-world documents due to spaces, newlines, digits, punctuation, English words, and (depending on document format) markup.
For example, if the last line of a text has a small number, it can be reasonably guessed to be referring to the date, where one of the words means "year" and, sometimes, a royal name also appears. Another case is when the text contains many small numbers, followed by a word, followed by a larger number; here, the word likely means "total" or "sum".
