Is there a way to determine if a specific character is 32 bits using JavaScript? I attempted to use charCodeAt() but it was unsuccessful for identifying 32-bit characters. Any guidance or assistance on this matter would be greatly valued.
Is there a way to determine if a specific character is 32 bits using JavaScript? I attempted to use charCodeAt() but it was unsuccessful for identifying 32-bit characters. Any guidance or assistance on this matter would be greatly valued.
When using the charCodeAt() method in JavaScript, it returns an integer value between 0 and 65535 (FFFF) which represents the UTF-16 code unit of a character.
If you need to get the entire code point value of a character, you can use the codePointAt() method instead.
You can determine whether a character is represented by 1 or 2 code point values by using the string.codePointAt(pos) method. Characters with values greater than FFFF require 2 code units, totaling 32 bits.
function is32Bit(c) {
return c.codePointAt(0) > 0xFFFF;
}
console.log(is32Bit("𠮷")); // true
console.log(is32Bit("a")); // false
console.log(is32Bit("￦")); // falseNote: Keep in mind that the codePointAt() method is part of ECMAScript 6, so it may not be supported in all browsers. For ECMAScript 6 compatibility, refer to firefox and chrome.
function characterDetails(ch) {
function is32Bit(character) {
return character.codePointAt(0) > 0xFFFF;
}
let information = `character: ${ch}\n` +
`CPx0: ${ch.codePointAt(0)}\n`;
if(ch.codePointAt(1)) {
information += `CPx1: ${ch.codePointAt(1)}\n`;
}
console.log( information += is32Bit(ch) ?
'Is 32 bit character.' :
'Is 16 bit character.');
}
//For testing
let ch16 = String.fromCodePoint(10020);
let ch32 = String.fromCodePoint(134071);
characterDetails(ch16);
characterDetails(ch32);
