Answers to Questions (FAQ)
What are the different types of characters?
According to the Unicode standard, which tends to standardize the character encoding, there are 6 classes of characters/type of characters:
Letters which may be uppercase, lowercase, or neither (non-Latin alphabets)
Example: ABCdefğhï (Accented letters are composed of a letter and a mark but are considered as a single letter in practice)
Digits including Arabic numerals, but there are also the Roman numerals, and others
Example: 0123
Symbols which include mathematical symbols, currency symbols, etc.
Example: +€$
Punctuation, dots, commas, dashes, and so on.
Example: ?;!,.
The separators which are spaces, line breaks, and so on.
Marks which are character modifiers (accents, diacritics, etc.)
Other, invisible characters, control characters, etc.
Why extracting some character types in a text?
In computer science, some characters are poorly managed, it is preferable to delete them.
In steganography, the use of certain characters can make it possible to hide a message in another.
What is the Unicode standard?
Unicode standardizes the computer encoding of texts in all languages at the international level. For the purpose of standardization, any character must be part of one of these 6 classes.
