Unicode is the most likely encoding standard used to represent international text data. Unicode is a universal character set that can encode over a million characters from different languages, scripts, symbols, and emojis.
Unicode supports multiple encoding forms, such as UTF-8, UTF-16, and UTF-32, that use different numbers of bytes to represent each character. Unicode enables consistent and interoperable representation and processing of text data across different platforms and applications.
