rustHow to use Unicode in a regex in Rust?

Using Unicode in a regex in Rust is easy and straightforward. The \p{<property>} syntax can be used to match any character that has the specified Unicode property. For example, the following code block will match any character that is a letter:

let re = Regex::new(r"\p{L}").unwrap();

Code explanation

• Regex::new: This is a static method of the Regex struct that creates a new Regex object from a given pattern.
• r"\p{L}": This is the regex pattern that matches any character that is a letter. The \p{<property>} syntax is used to match any character that has the specified Unicode property.
• unwrap: This is a method of the Result type that returns the contained value of a Result if it is Ok, or panics if it is Err.
