Invalid [] range "%s" in regex; marked by <-- HERE in m/%s/

(F) The range specified in a character class had a minimum character greater than the maximum character. One possibility is that you forgot the {} from your ending \x{} - \x without the curly braces can go only up to ff. The <-- HERE shows in the regular expression about where the problem was discovered. See 11.
