Frequently asked questions

What is Unicode?
Unicode is a unified character encoding standard that provides unique numbers for all characters in the world, supporting multilingual text representation. It's the foundation of text processing in modern software development.
What's the difference between \u and U+ formats?
They are just different notation styles: \uXXXX is JavaScript/programming style, U+XXXX is standard Unicode notation. They represent the same Unicode code points.
What Unicode ranges are supported?
Supports all characters in the Basic Multilingual Plane (BMP, U+0000 to U+FFFF), including Chinese, Japanese, Korean, emoji, and other commonly used characters.
Why does garbled text appear?
Garbled text usually results from encoding and decoding using different character sets. Ensuring both sender and receiver use UTF-8 can prevent most encoding issues.
How to handle emoji?
Emoji are usually in supplementary planes and require surrogate pairs, represented as \uD83D\uDE00 style double sequences.
