Unicode Converter
Convert between Unicode, UTF-8, and hex representations
About the Unicode Converter
Unicode is the universal character encoding standard that supports over 143,000 characters from 154 modern and historic scripts, including emojis, mathematical symbols, and special characters. Every character in Unicode has a unique code point—a number that identifies it uniquely. Understanding Unicode code points is essential for internationalization (i18n), character encoding debugging, and working with multilingual applications.
The Unicode Converter on UniversalDevTools.in is a professional-grade utility that converts between text and Unicode code points in multiple formats. Unicode code points are typically represented in hexadecimal notation (like U+0041 for 'A' or U+1F600 for 😀), but this tool also supports decimal representation and various encoding formats. This bidirectional conversion is essential for developers building applications that support multiple languages, emojis, and special symbols.
Internationalization (i18n) development requires understanding how characters are encoded and represented. When building applications for global audiences, developers must handle characters from different scripts—Latin, Cyrillic, Arabic, Chinese, Japanese, Korean, and hundreds more. Unicode code points allow developers to reference characters unambiguously, regardless of how they're displayed or stored in different encoding formats (UTF-8, UTF-16, UTF-32).
Character encoding debugging is another critical use case. When text displays incorrectly (showing question marks, boxes, or garbled characters), it's often an encoding issue. Converting text to Unicode code points helps identify the exact characters being used, allowing developers to diagnose encoding mismatches, font rendering issues, and data corruption problems.
All conversion happens entirely in your browser using JavaScript. Your text—whether it's multilingual content, emoji sequences, or sensitive data—never leaves your device or gets transmitted to external servers. This privacy-first approach ensures complete confidentiality for proprietary content, user data, and any text requiring secure processing.

Questions
- How do I convert text to Unicode?
- Select 'Text → Unicode' mode and enter your text. Each character is converted to its Unicode code point in U+XXXX format (e.g., 'A' becomes 'U+0041').
- What is a Unicode code point?
- A Unicode code point is a unique number assigned to each character in the Unicode standard. It's written as U+ followed by hexadecimal digits (e.g., U+1F600 for 😀).
- How do I find the Unicode of an emoji?
- Paste the emoji in the input field with 'Text → Unicode' mode. The tool will display its Unicode code point (e.g., 😀 = U+1F600).
- What is the difference between Unicode and UTF-8?
- Unicode is a character set assigning numbers to characters. UTF-8 is an encoding that represents those numbers as bytes. UTF-8 is the most common Unicode encoding on the web.
- How many characters does Unicode support?
- Unicode currently defines over 143,000 characters covering 154 scripts, including emojis, mathematical symbols, ancient scripts, and characters from virtually all writing systems.
