| Unicode table - List of most common Unicode characters * | |
| * This summary list contains about 2000 characters for most common ocidental/latin languages and most printable symbols but not chinese, japanese, arab, archaic and some unprintable. | |
| Contains character codes in HEX (hexadecimal), decimal number, name/description and corresponding printable symbol. | |
| What is Unicode? | |
| Unicode is a standard created to define letters of all languages and characters such as punctuation and technical symbols. Today, UNICODE (UTF-8) is the most used character set encoding (used by almost 70% of websites, in 2013). The second most used character set is ISO-8859-1 (about 20% of websites), but this old encoding format is being replaced by Unicode. | |
| How to identify the Unicode number for a character? | |
