Practical Applications

Determining Unicode code points empowers various tasks:

  • Character Analysis: Analyze language distribution by counting code points within specific ranges.
  • Text Encoding: Convert text between different encodings like UTF-8 and UTF-16 based on code point values.
  • Font Development: Ensure fonts correctly display characters by mapping code points to glyphs.
  • Emojis and Special Characters: Work with emojis and special characters effectively by using their code points.


JavaScript Program to Determine the Unicode Code Point at a Given Index

It is important to know what the Unicode code points are before moving on to the JavaScript implementation. A Unicode code point is a distinct integer value that represents each character in a string. A programmer may easily manipulate strings using JavaScript’s techniques for working with these code points.

Using the codePointAt() Method

JavaScript provides the codePointAt() method for strings, which returns the Unicode code point of the character at a specified index. The index refers to the position of the character in the string, starting from 0....

Using the fromCodePoint() Method

The charCodeAt() method returns the code unit at a given index, while codePointAt() clearly gets the single-character Unicode code point. Remember that JavaScript strings employ UTF-16 encoding, and that certain characters that are not part of the Basic Multilingual Plane (BMP) call for two code units, or surrogate pairs, which are represented by separate charCodeAt() values....
