Schmaltzy corner case for Pig Latin

I coded my solution to Pig Latin by looking at the first, second or third character of the input word and testing whether these were vowels or not. This solution passed the tests. However it occurred to me that there might be words that start with four consonants. Of course, there’s a regex for that! –https://visca.com/regexdict/ Schmaltzy is an example, as is chthonic and schlockmeister. hehe
