What's Unicode?

Unicode (Georges/Unified Code) is a computer industry standard designed to provide the only digital identifier for almost all the world's text systems. Before Unicode appeared, hundreds of different coding systems (e.g. ASCII, GB2312, Big5, etc.) existed, and there was frequent confusion in the transmission of documents between different language settings due to inconsistent codes. The emergence of Unicode has solved the problem in its fundamental sense, assigning a single code point (Code Point) to every character, Emoji and even a special control symbol.

Common character encoding format

  • Unicode conversion (\\XXXX): Source code often used in programming languages such as JavaScript, Java, Python. For example, the unicode transposer for the Hanja word "you" is \u4f60。
  • HTML entity (#xXXX;): For web development. This format is used when certain characters are not directly displayed on the web page (or to avoid HTML injections). For example: 😀 - It's a sign of twilight.
  • UTF-8： A variable length character encoding for Unicode. It is the most widely used code on the Internet at present, as it is highly effective in expressing multinational languages while being compatible with ASCII.
  • Base64： Although Base64 is not a character encoding per se, it is often used to convert binary data (or Unicode string) to a pure text format for transmission in an agreement that does not support a special character (e.g. Email).

How can this tool be debugged?

1. Fix the holster code: If you see something like that in the code, \u6b22\u8fce This string, which is pasted to the input box, automatically returns the tool as " Welcome " .

2. Get Emoji code: Want to use specific Emoji on a web page or application? A direct paste to Emoji allows you to access its code points and HTML physical codes.

3. Encoding Analysis: character details will be disassembled with each character. This is very useful for developers in debugging some invisible characters (e.g., zero wide spaces ZWSP) or distinguishing between similar symbols.

Developer Hint

When processing Unicode, note the difference between " code elements " and " code points " . In JavaScript,length The attribute returns the number of code elements, and a character may be two yards long for characters that exceed the basic multi-linguistic plane (BMP) (e.g., most Emoji). This tool uses modern CMAScript norms that correctly identify and process all plane points.
