Unicode

Latin Capital Letter Thorn, Þ, has the number U+00DE

Unicode is an international standard on how to encode characters. All characters on a computer are stored and sent using numbers. Unicode gives each character a number. Picture a very big table that has most of the worlds symbols and letters, each with a number. Everyone uses the same number for each symbol. This is important for people talking to each other using different devices. When someone in France on an iPad emails someone in Egypt on an Android, the same characters must appear both the screens.

Arabic-Indic Numbers

Unicode is pretty big now. It has 137,439 characters, each with its own unicode number. Take a look at part of the Arabic script, used by people who write in Arabic, Kurd and Persian.

Arabic Letter Dotless Qaf,ٯ , has the number U+066F

For example, the symbols for the Arabic-Indic digits 0-9 are stored as:

Translation	0	1	2	3	4	5	6	7	8	9
Arabic-Indic	٠	١	٢	٣	٤	٥	٦	٧	٨	٩
Unicode	U+0660	U+0661	U+0662	U+0663	U+0664	U+0665	U+0666	U+0667	U+0668	U+0669
