What is the significance of the rune data type in Go?
- It represents floating-point numbers.
- It's an alias for the int32 data type.
- It's used exclusively for error handling.
- It's used for text and character encoding.
The rune data type in Go is significant because it's used for representing Unicode characters, making it suitable for text and character encoding. Unlike many other programming languages, which use char or byte for characters, Go uses rune, which ensures proper handling of Unicode characters. This is essential for internationalization and multilingual applications, where different character sets and symbols need to be correctly processed and displayed.
