This is a test project to demonstrate how to check for control characters in Unicode strings. This can be handy to check input data from an untrusted source.
The "go-unicode-control-check" package is a tool that allows Go developers to detect control characters within Unicode strings. Control characters are characters that do not represent a printable symbol, but instead serve to control the display or processing of text. This package can be useful for preventing security vulnerabilities, as control characters can be used for malicious purposes such as injection attacks.
To install the package, run the following command:
go get github.com/cwansart/go-unicode-control-check
To use the package, import it into your Go code:
import "github.com/cwansart/go-unicode-control-check"The package provides a single function, HasControlCharacter, which takes a string as input and returns a boolean indicating whether the string contains any control characters. Here is an example usage:
package main
import (
"fmt"
check "github.com/cwansart/go-unicode-control-check"
)
func main() {
containsControlChars := check.ContainsControlRune("Hello, world!")
if containsControlChars {
fmt.Println("String contains control characters.")
} else {
fmt.Println("String does not contain control characters.")
}
