Unicode alias names and abbreviations

Unicode is a system used to represent letters, numbers, and other symbols. Different types of computers and programs sometimes use different ways to display Unicode characters, but they are all readable by people. Unicode alias names and abbreviations are used to tell computers which type of Unicode character to display. For example, the letter 'A' might have an alias name of 'Latin Capital Letter A', or an abbreviation of 'U+0041'. This helps computers make sure everyone sees the same characters no matter what type of computer or program they have.
