Have you ever struggled to find the correct encoding for a special symbol while writing documents, designing interfaces, or developing websites? By querying a built-in Unicode character database, this tool allows you to quickly get the corresponding Unicode code point (e.g., U+00A9) and HTML entity (e.g., © or ©) by entering the symbol's name (like "copyright") or the symbol itself. Unicode is a universal character encoding standard that defines a unique code point for every character and symbol across all writing systems worldwide. HTML entities are escape sequences defined to safely and consistently display these special characters on web pages.
Q: How do I find the encoding for the "€" symbol?
Simply type "€" or enter the name "Euro" in the search box. The results will show its Unicode as U+20AC and its HTML entity as € or €.
Q: Why do some characters look different on different devices?
The visual appearance of a character depends on the font used by the system or web page. Unicode only defines the "identity" (code point) of a character; the specific glyph is determined by the font file. To ensure consistent display in web development, it is recommended to use web-safe fonts or import a font containing that character via @font-face.
When using copied HTML entities, ensure they are used within the context of an HTML/XML document. Some extremely rare or newly added characters in the Unicode standard may not be included in this tool's database. In plain text environments (like code comments or configuration files), it is usually more convenient to use Unicode characters directly. However, on web pages, characters with special meanings like "<", ">", and "&" must use HTML entities (e.g., <, >, &) to prevent parsing errors.
For front-end developers handling user input or dynamic content, if you need to safely insert text containing unknown special characters into the DOM, consider using the .textContent property instead of .innerHTML. The former automatically handles text content, while the latter requires you to manually convert characters like "<" and "&" into HTML entities. A typical use case for this tool: search for "trademark" to find the ™ symbol, which has a Unicode of U+2122 and an HTML entity of ™ or ™, commonly used to indicate a registered trademark.
