인코딩 변환기

The Encoding Converter takes any single character and shows its representation in every common encoding format: HTML named entity, HTML decimal reference, HTML hex reference, CSS escape, JavaScript escape, Python escape, and raw UTF-8 bytes. All values can be copied with one click.

Type or paste one character into the input field and the tool instantly displays a table of all encoding formats for that character. Click Copy next to any row to copy that specific encoding to your clipboard.

The tool outputs HTML entity (e.g., ©), HTML decimal (e.g., ©), HTML hex (e.g., ©), CSS content escape (e.g., \A9), JavaScript string escape (e.g., \u00A9), Python string escape (e.g., \u00a9), and the U+ codepoint notation.

Developers use it when embedding special characters in HTML, CSS content properties, JavaScript strings, or Python source code and need the exact escape syntax for each language. It removes the need to look up encoding tables in documentation.

Both are numeric character references that browsers interpret identically. HTML decimal uses base-10 (e.g., € for the euro sign) while HTML hex uses base-16 with an x prefix (e.g., €). The hex format aligns with Unicode codepoint notation.

CSS uses a backslash followed by the hex codepoint (e.g., \20AC) in properties like content or font-face. HTML uses ampersand-based references (e.g., €). The Encoding Converter shows both formats so you can paste the right one into your stylesheet or markup.

Yes — characters above U+FFFF are fully supported. The tool calculates the correct JavaScript surrogate pair escape, the Python \U escape for 8-digit codepoints, and the correct UTF-8 byte sequence for all supplementary plane characters.

The character input and encoding computation run entirely in your browser, so basic conversions work offline once the page is loaded. The initial page load requires a network connection.

A CSS content escape is the syntax used in the CSS content property to insert a Unicode character, written as a backslash followed by the hex codepoint (e.g., content: '\2713' for a checkmark). It is commonly used with pseudo-elements like ::before and ::after.

Unicode Lookup starts from a codepoint and shows you the character. The Encoding Converter starts from a character (which you type or paste) and shows you all its encoding representations. For a combined workflow, use Lookup to find the character and then Encoding Converter to get the right syntax for your code.
