Unicode Encoder

What Is Unicode Encoder?

A Unicode Encoder converts characters in a text string into their corresponding Unicode code points. Unicode provides a standard way of representing characters from writing systems, symbols, punctuation and other character sets across different computers, applications and platforms. A code point is a numerical value assigned to a Unicode character and is commonly written in hexadecimal notation with a U+ prefix.

This tool is useful for developers, web designers, programmers, technical writers and anyone who needs to inspect or document the Unicode values associated with text. It can be particularly helpful when debugging character encoding issues, examining unusual characters, working with source code or preparing Unicode references for technical documentation.

Why Use Unicode Encoder?

The Unicode Encoder provides a quick way to inspect the underlying Unicode code points represented by text without installing specialist software or manually looking up individual characters.

How to Use Unicode Encoder

Converting text into Unicode code points only takes a few steps. You can choose the notation that best suits your development or documentation task.

1. Enter your text — Type or paste the characters you want to inspect into the input field.
2. Choose an output format — Select U+ hexadecimal, hexadecimal or decimal Unicode notation.
3. Encode the text — Click Encode Unicode to generate the code point for each Unicode character.
4. Copy the result — Click Copy Result to place the generated Unicode values on your clipboard.

Unicode assigns code points to characters so that text can be represented consistently across different systems and languages. Unicode code points are conventionally written in hexadecimal notation using a U+ prefix. For example, the capital letter A has the Unicode code point U+0041, while the euro sign has the code point U+20AC.

Unicode code points can also be represented as decimal values. The code point for A is 65 in decimal, while its hexadecimal representation is 0041. This tool lets you switch between these common representations so you can use the output in programming, documentation, debugging and character-reference workflows.

Unicode U+ Notation

U+ notation is one of the most recognisable ways to identify Unicode code points. The U+ prefix is followed by a hexadecimal number. For example, U+0041 identifies A, U+00E9 identifies é, and U+1F600 identifies the grinning face emoji. This notation is widely used in Unicode documentation and technical discussions.

Unicode Decimal and Hexadecimal Values

Every Unicode code point has a numerical value that can be expressed in different number systems. Decimal uses base 10, while hexadecimal uses base 16. For example, the letter A is decimal 65 and hexadecimal 41. The hexadecimal representation is commonly written as U+0041 when identifying the Unicode code point.

Unicode Encoding and Character Representation

A Unicode code point identifies a character, but it is not the same thing as a particular character encoding format such as UTF-8, UTF-16 or UTF-32. Unicode defines the character repertoire and code points, while encoding formats determine how those code points are represented as bytes or code units for storage and transmission.

This Unicode Encoder reports Unicode code points rather than converting text into UTF-8 or another byte-level encoding. It processes Unicode characters correctly when they are represented by multiple JavaScript UTF-16 code units, allowing characters such as many emoji to be treated as a single Unicode code point. The result is intended for inspection, development and documentation rather than cryptographic or security purposes.
