JavaScript and Unicode

Tuesday May 29, 2007
JavaScript can use Unicode characters

The ASCII character set is limited to 128 different characters and 32 of those are reserved for control characters. Unicode solves this shortage by using one, two, or even four bytes to allow for over sixteen million different characters and symbols. JavaScript can't use all of the Unicode characters but it can work with the 65000 most common ones.
