Frequently Asked Questions
What is the difference between ASCII and Unicode?
ASCII is a 7-bit encoding that represents 128 characters (0-127), including English letters, digits, and basic symbols. Unicode is a universal standard that can represent over 140,000 characters from all writing systems worldwide, including emojis and special symbols.
What format does Unicode output use?
Unicode output uses the standard U+XXXX format, where XXXX is the hexadecimal code point. For example, the letter A is U+0041, and the emoji π is U+1F30D. This format is widely used in documentation and programming.
How do I convert emoji to Unicode?
Simply paste the emoji in the input field with Text to Unicode selected. The tool will show the Unicode code point. For example, π converts to U+1F30D. You can also decode U+1F30D back to the emoji.
What are HTML entities used for?
HTML numeric entities (like A for A) are used to display special characters in HTML that might otherwise be interpreted as code. They ensure characters display correctly regardless of the pages encoding.
