pub fn validate_and_sanitize_string(
    string: &str,
    allow_new_line: bool,
) -> ResponseResult<String>
Expand description

Validates a given string to contain only text characters (from any language), and no control characters, thus making it safe to display in a web page IF IT IS THEN PROPERLY ESCAPED, AS AN ADDITIONAL STEP. THIS METHOD DOES NOT ESCAPE FOR HTML, JAVASCRIPT, OR ANY OTHER LANGUAGE. If allow_new_line is set to true, then \n and \r are allowed, but \r is removed. If a string contains control characters (other than \n and \r when allow_new_line is true) then a ResponseResult that allows 400 Bad Request to be propagated is returned. If you prefer to use your own error handling, you can simply match on the Err variant and interpret as documented here.
