What is fromCharCode?
fromCharCode() method returns a string created from the specified sequence of UTF-16 code units.
What is charCodeAt?
fromCharCode() method converts Unicode values to characters. The String. fromCharCode() is a static method of the String object. The syntax is always String.
What is UTF-16 format?
UTF-16 (16-bit Unicode Transformation Format) is a character encoding capable of encoding all 1,112,064 valid character code points of Unicode (in fact this number of code points is dictated by the design of UTF-16).
What is UTF-16 Le encoding?
UTF-16LE: A character encoding that maps code points of Unicode character set to a sequence of 2 bytes (16 bits). UTF-16LE stands for Unicode Transformation Format – 16-bit Little Endian. Each block is converted to a 16-bit integer assuming the least significant byte first.
What is fromcharcode () in Java?
Because fromCharCode () is a static method of String, you always use it as String.fromCharCode (), rather than as a method of a String object you created. In UTF-16, the most common characters can be represented by a single 16-bit value (i.e. a code unit).
What is the range of string fromcharcode in Java?
The static String.fromCharCode () method returns a string created from the specified sequence of UTF-16 code units. A sequence of numbers that are UTF-16 code units. The range is between 0 and 65535 ( 0xFFFF ). Numbers greater than 0xFFFF are truncated.
Why charcodeat method does not work with UTF-8 encoded string?
The charCodeAt method provides only ascii/utf-16 encoding even with utf-8 encoded String object : Building the string with fromCharCode would not be right as it expects UTF-16 : Here is a simple example to encode and decode UTF8 bytes and ASCII bytes :
