Frequently Asked Questions
Unicode is a universal character encoding standard that assigns a unique number to every character across all writing systems. It is the foundation of all modern text processing on the web.
Unicode encoding converts each character into its escape sequence format. For example, the Chinese character for "good" becomes backslash-u597D. This format is used in JavaScript, Java, and Python source code.
All Unicode characters including Chinese (CJK), Japanese, Korean, Arabic, Cyrillic, emoji, and mathematical symbols. Any text you can type can be encoded or decoded.
When embedding non-ASCII text in source code, creating portable data formats, debugging character encoding issues, or working with APIs that require ASCII-safe string representations.
